Description:
BACKGROUND OF THE INVENTION 
     Liquid crystal displays use mixtures of liquid crystals having desired material properties such as operating temperature range, thermal stability, light stability, switching time, and contrast ratio. The material properties of the mixtures are determined by the constituents of the mixtures. 
     The demand for liquid crystal displays having improved performance has increased. In particular, liquid crystal mixtures having low threshold voltage are desired, especially for display applications. The threshold voltage is the amount of voltage across a pixel to produce a response. Addressing pixels with lower voltages allows simplification of the electronics used, resulting in the possibility for space and weight savings. The threshold voltage is inversely proportional to the dielectric anisotropy of the mixture. Therefore, one way to improve the properties of a liquid crystal mixture having low threshold voltage should be the use of polar liquid crystal components in the mixtures, to increase the dielectric anisotropy of the mixture. 
     Improved polar liquid crystal components are needed.

     EXPERIMENTAL 
       F 3 Ph.Ch.C 2 H 2 OMe 
     Potassium-t-butoxide (42 ml, 1M in THF, 42 mmol) was added dropwise over 15 min to a stirred, cooled (−5° C.) slurry of MeOCH 2 PPh 3 .Cl (13.6 g, 39.7 mmol) in dry THF (80 ml) under argon. The reaction mixture was maintained under these conditions for 2 h. To the resulting deep orange reaction mixture a solution of PCFFFL (9.4 g, 39 mmol) in dry THF (25 ml) was added dropwise, and the resulting reaction mixture was stirred for 16 h at room temp. Water (60 ml) was added to the reaction mixture, extracted with 3×75 ml hexane, the combined organic extract washed with water, dried (MgSO 4 ), and filtered over a bed of celite. The solvent was removed in vacuo to yield yellow liquid. The crude liquid was taken up in hexane/ethyl acetate (90/10, 50 ml) and filtered down a short silica gel column and washing down with hexane/EA (90/10, 250 ml). The solvent was removed in vacuo yield a pale yellow liquid; yield, 9.7 g. Crystallization from hexane (20 ml) at −20° C. gave white solid. Yield, 6.1 g.
 
F 3 Ph.Ch.CH 2 CHO
 
     A mixture of F 3 Ph.Cy.C 2 H 2 OMe (6.1 g, 22.6 mmol), acetone (80 ml) and HCl (3N, 55 ml) was stirred at room temp. for 2 h. The reaction mixture was extracted with 3×50 ml ethyl acetate, the organic extract washed with water, saturated solution of NaHCO 3 , water, dried (MgSO 4 ), and filtered over celite. The solvent was removed in vacuo to yield a clear liquid. Yield, 5.7 g.
 
F 3 Ph.Ch.CH 2 CHOH.Cp
 
     A solution of F 3 Ph.Ch.CH 2 CHO (5.7 g, 22.3 mmol) in dry ether (30 ml) was added dropwise over 15 min to a stirred, cooled (ice bath) solution of cyclopentylmagnesium bromide (15 ml, 2.0M in ether, 30 mmol). The reaction mixture was maintained under these conditions for 2 h, and 20% H 2 SO 4  (25 ml) was added slowly and the mixture allowed to warm to room temp. Ether (20 ml) was added, organic phase washed with 2×20 ml NaHCO 3 , water, dried (MgSO 4 ) and filtered over a bed of silica gel. The solvent was removed in vacuo to yield a pale thick liquid. Yield, 6.7 g. Crystallization from hexane (20 ml, in fridge overnight) gave the product as a white solid. Yield, 4.1 g.
 
F 3 Ph.Ch.CH 2 CO.Cp
 
     A solution of F 3 Ph.Ch.CH 2 CHOH.Cp (1.0 g, 3 mmol) in dry CH 2 Cl 2  (10 ml) was added to a slurry of PCC (1.0 g, 4.6 mmol) in dry CH 2 Cl 2  (15 ml), and the resulting dark brown reaction mixture was stirred at room temp. for 3 h. Hexane (30 ml) was added resulting in a brown precipitate. The reaction mixture was filtered over a bed of celite, washed with hexane (25 ml). The solvent was removed in vacuo to yield a clear liquid; yield, 1.0 g. The liquid was taken up in hexane (10 ml), loaded onto a short silica gel column, and washed down with a mixture of hexane/EA (90/10, 150 ml). The solvent was removed in vacuo to give a clear thick liquid; yield, 1.0 g. Crystallization from hexane (5 ml, in freezer overnight), gave the product as a white solid; yield, 0.52 g, 99.6% GC purity.

     All references throughout this application, for example patent documents including issued or granted patents or equivalents; patent application publications; and non-patent literature documents or other source material; are hereby incorporated by reference herein in their entireties, as though individually incorporated by reference, to the extent each reference is at least partially not inconsistent with the disclosure in this application (for example, a reference that is partially inconsistent is incorporated by reference except for the partially inconsistent portion of the reference). 
     All patents and publications mentioned in the specification are indicative of the levels of skill of those skilled in the art to which the invention pertains. References cited herein are incorporated by reference herein in their entirety to indicate the state of the art, in some cases as of their filing date, and it is intended that this information can be employed herein, if needed, to exclude (for example, to disclaim) specific embodiments that are in the prior art. For example, when a compound is claimed, it should be understood that compounds known in the prior art, including certain compounds disclosed in the references disclosed herein (particularly in referenced patent documents), are not intended to be included in the claim. 
     When a group of substituents is disclosed herein, it is understood that all individual members of those groups and all subgroups, including any isomers and enantiomers of the group members, and classes of compounds that can be formed using the substituents are disclosed separately. When a compound is claimed, it should be understood that compounds known in the art including the compounds disclosed in the references disclosed herein are not intended to be included. When a Markush group or other grouping is used herein, all individual members of the group and all combinations and subcombinations possible of the group are intended to be individually included in the disclosure. 
     Every formulation or combination of components described or exemplified can be used to practice the invention, unless otherwise stated. Specific names of compounds are intended to be exemplary, as it is known that one of ordinary skill in the art can name the same compounds differently. When a compound is described herein such that a particular isomer or enantiomer of the compound is not specified, for example, in a formula or in a chemical name, that description is intended to include each isomers and enantiomer of the compound described individual or in any combination.

     As used herein, “comprising” is synonymous with “including,” “containing,” or “characterized by,” and is inclusive or open-ended and does not exclude additional, unrecited elements or method steps. As used herein, “consisting of” excludes any element, step, or ingredient not specified in the claim element. As used herein, “consisting essentially of” does not exclude materials or steps that do not materially affect the basic and novel characteristics of the claim. Any recitation herein of the term “comprising”, particularly in a description of components of a composition or in a description of elements of a device, is understood to encompass those compositions and methods consisting essentially of and consisting of the recited components or elements. The invention illustratively described herein suitably may be practiced in the absence of any element or elements, limitation or limitations which is not specifically disclosed herein. 
     The terms and expressions which have been employed are used as terms of description and not of limitation, and there is no intention in the use of such terms and expressions of excluding any equivalents of the features shown and described or portions thereof, but it is recognized that various modifications are possible within the scope of the invention claimed.
