Question: What is formed through a reaction of (CH)C(CHOH) and Carbonyl Chloride?
Context: Twin-wall plastic, specifically twin-wall polycarbonate, is an extruded multi-wall polymer product created for applications where its strength, thermally insulative properties, and moderate cost are ideal.  Polycarbonate, which is most commonly formed through the reaction of Bisphenol A and Carbonyl Chloride, is an extremely versatile material.  It is significantly lighter than glass, while managing to be stronger, more flexible, and more impact resistant.  Twin-wall polycarbonate is used most commonly for green houses, where it can support itself in a structurally sound configuration, limit the amount of UV light due to its nominal translucence, and can withstand the rigors of daily abuse in an outdoor environment.  The stagnant air in the cellular space between sheets provides insulation, and additional cell layers can be extruded to enhance insulative properties at the cost of light transmission. Bisphenol A (BPA) is an organic synthetic compound with the chemical formula (CH)C(CHOH) belonging to the group of diphenylmethane derivatives and bisphenols, with two hydroxyphenyl groups.  It is a colorless solid that is soluble in organic solvents, but poorly soluble in water.  It has been in commercial use since 1957. In organic chemistry, the Cieplak effect is a predictive model that explains why nucleophiles preferentially add to one face of a carbonyl over another.  Proposed by Andrzej Stanislaw Cieplak in 1980, it explains anomalous results that other models of the time, such as the Cram and Felkin–Anh models, can't justify.  In the Cieplak model, electrons from a neighboring bond delocalize into the forming carbon–nucleophile (C–Nuc) bond, lowering the energy of the transition state and accelerating the rate of reaction.  Whichever bond can best donate its electrons into the C–Nuc bond determines which face of the carbonyl the nucleophile will add to.  The nucleophile may be a number of reagents, most commonly organometallic or reducing agents.  The Cieplak effect is subtle, and often competes with sterics, solvent effects, counterion complexation of the carbonyl oxygen, and other effects to determine product distribution. The Henry Reaction (also referred to as the nitro-aldol reaction) is a classic carbon–carbon bond formation reaction in organic chemistry.  Discovered in 1895 by the Belgian chemist Louis Henry (1834-1913), it is the combination of a nitroalkane and an aldehyde or ketone in the presence of a base to form β-Nitro alcohols.  This type of reaction is commonly referred to as a "nitro-aldol" reaction (nitroalkane, aldehyde, and alcohol) It is nearly analogous to the aldol reaction that had been discovered 23 years prior that couples two carbonyl compounds to form β-hydroxy carbonyl compounds known as "aldols" (aldehyde and alcohol).  The Henry reaction is a useful technique in the area of organic chemistry due to the synthetic utility of its corresponding products, as they can be easily converted to other useful synthetic intermediates.  These conversions include subsequent dehydration to yield nitroalkenes, oxidation of the secondary alcohol to yield α-nitro ketones, or reduction of the nitro group to yield β-amino alcohols. Imidoyl halides are synthesized by combining amides and halogenating agents.  The structure of the carboxylic acid amides plays a role in the outcome of the synthesis.Imidoyl chloride can be prepared by treating a monosubstituted carboxylic acid amide with carbonyl chloride. The McMurry reaction is an organic reaction in which two ketone or aldehyde groups are coupled to an alkene using titanium chloride compound such as titanium(III) chloride and a reducing agent.  The reaction is named after its co-discoverer, John E. McMurry.  The McMurry reaction originally involved the use of a mixture TiCl and LiAlH, which produces the active reagent(s).  Related species have been developed involving the combination of TiCl or TiCl with various other reducing agents, including potassium, zinc, and magnesium.  This reaction is related to the Pinacol coupling reaction which also proceeds by reductive coupling of carbonyl compounds. The Barbier reaction is an organic reaction between an alkyl halide and a carbonyl group as an electrophilic substrate in the presence of magnesium, aluminium, zinc, indium, tin or its salts.  The reaction product is a primary, secondary or tertiary alcohol.  The reaction is similar to the Grignard reaction but the crucial difference is that the Barbier reaction is a one-pot synthesis whereas a Grignard reagent is prepared separately before addition of the carbonyl compound.  Barbier reactions are nucleophilic addition reactions that usually take place with relatively inexpensive and water insensitive metals or metal compounds in contrast to Grignard reagents or organolithium reagents. For this reason it is possible in many cases to run the reaction in water which makes the procedure part of green chemistry.  The Barbier reaction is named after Victor Grignard's teacher Philippe Barbier. Alkylimino-de-oxo-bisubstitution in organic chemistry is the organic reaction of carbonyl compounds with amines to imines.  The reaction name is based on the IUPAC Nomenclature for Transformations.  The reaction is acid catalyzed and the reaction type is nucleophilic addition of the amine to the carbonyl compound followed by transfer of a proton from nitrogen to oxygen to a stable hemiaminal or carbinolamine.  With primary amines water is lost in an elimination reaction to an imine.  With aryl amines especially stable Schiff bases are formed. The Rubottom oxidation is a useful, high-yielding chemical reaction between silyl enol ethers and peroxyacids to give the corresponding α-hydroxy carbonyl product.  The mechanism of the reaction was proposed in its original disclosure by A.G. Brook with further evidence later supplied by George M. Rubottom.  After a Prilezhaev-type oxidation of the silyl enol ether with the peroxyacid to form the siloxy oxirane intermediate, acid-catalyzed ring-opening yields an oxocarbenium ion.  This intermediate then participates in a 1,4-silyl migration (Brook rearrangement) to give an α-siloxy carbonyl derivative that can be readily converted to the α-hydroxy carbonyl compound in the presence of acid, base, or a fluoride source. Rhodium carbonyl chloride is an organorhodium compound with the formula RhCl(CO).  It is a red-brown volatile solid that is soluble in nonpolar organic solvents.  It is a precursor to other rhodium carbonyl complexes, some of which are useful in homogeneous catalysis.
