Substituent Effects on Oxidation‐Induced Formation of Quinone Methides from Arylboronic Ester Precursors
Authors: Cao Sheng , Christiansen Robin , Peng Xiaohua 
Published: May 2013

AbstractA series of arylboronic esters containing different aromatic substituents and various benzylic leaving groups (Br or N+Me3Br−) have been synthesized. The substituent effects on their reactivity with H2O2 and formation of quinone methide (QM) have been investigated. NMR spectroscopy and ethyl vinyl ether (EVE) trapping experiments were used to determine the reaction mechanism and QM formation, respectively. QMs were not generated during oxidative cleavage of the boronic esters but by subsequent transformation of the phenol products under physiological conditions. The oxidative deboronation is facilitated by electron‐withdrawing substituents, such as aromatic F, NO2, or benzylic N+Me3Br−, whereas electron‐donating substituents or a better leaving group favor QM generation. Compounds containing an aromatic CH3 or OMe group, or a good leaving group (Br), efficiently generate QMs under physiological conditions. Finally, a quantitative relationship between the structure and activity has been established for the arylboronic esters by using a Hammett plot. The reactivity of the arylboronic acids/esters and the inhibition or facilitation of QM formation can now be predictably adjusted. This adjustment is important as some applications may benefit and others may be limited by QM generation.
Bulky Phosphinines: From a Molecular Design to an Application in Homogeneous Catalysis

Published: May 2013

AbstractThe design and preparation of an asymmetrically substituted and bulky phosphinine was achieved by introducing sterically demanding substituents into specific positions of a rigid phosphorus‐heterocyclic framework. Compound 5 shows, at the same time, axial chirality and a sufficiently high energy barrier for internal rotation to prevent enantiomerization. Both enantiomers of 5 were isolated by means of chiral analytical HPLC, and their absolute configurations could be assigned by combining experimental data and DFT calculations. Despite its substitution pattern, 5 can still coordinate to transition‐metal centers through the lone pair of electrons on the phosphorus atom. Rapid CH activation on the adjacent aryl substituent at the 2‐position of the phosphorus heterocycle was achieved by using [{Cp*IrCl2}2] (Cp*=1,2,3,4,5‐pentamethylcyclopentadienyl) as a metal precursor. A racemic mixture of 5 was applied as a π‐accepting low‐coordinate phosphorus ligand in the Rh‐catalyzed hydroformylation of trans‐2‐octene, which showed a clear preference for the formation of 2‐methyloctanal.
Bispidine Platform Grants Full Control over Magnetic State of Ferrous Chelates in Water
Authors: Kolanowski Jacek Lukasz , Jeanneau Erwann , Steinhoff Robert , Hasserodt Jens 
Published: May 2013

AbstractA bicyclic ligand platform for iron(II), which allows total control over the complex’s magnetic properties in aqueous solution simply by varying one of the six coordination sites of the bispidine ligand, is reported. To achieve this, an efficient synthetic route to an N5 bispidine framework (ligand L4) that features an unsubstituted N‐7 site is established. Then, by choosing appropriate N‐7‐coordinating substituents, the spin state of choice can be imposed on the corresponding ferrous complexes under environmentally relevant conditions in water and near‐room temperature. Importantly, the first low‐spin and diamagnetic iron(II) chelates in the bispidine series, both in the solid state and in aqueous solution, are reported. The eradication of head‐on steric clashes between pendent coordinating arms is at the origin of this success. A new pair of constitutionally similar ferrous coordination compounds of a multidentate ligand system is obtained, which exhibits a distinctly binary (off–on) magnetic relationship. The new synthetic intermediate L4 may be substituted in just one step by any desired pendent arm, thus allowing access to complexes with finely tuned magnetic properties.
A Versatile Dithienylethene‐Functionalized Ph‐Diazabutadiene (DAB) Ligand: From Photoswitchable Main‐Group Molecules to Photochromic Polymers
Authors: Price Jacquelyn T. , Ragogna Paul J. 
Published: May 2013

AbstractWithin the past decade photochromic materials, specifically dithienylethenes (DTEs), have received increased interest because of their ability to function as potential photoswitchable molecular devices and optical memory storage systems. Current research in this area has focused on incorporating organic architectures to functionalize the DTE framework and alter the resulting photophysical properties; however, their syntheses are often not trivial. In this context, we have designed a simple and versatile diimine (2) containing adjacent 2,5‐dimethyl(thienyl) rings in the backbone. This redox active diimine (2) acts as a precursor to a novel photochromic ligand and has been used to coordinate to both boron and phosphorus elements, along with the synthesis of a phosphorane‐side‐chain functionalized polymer without further functionalization to the parent DTE framework. A study of the resulting photochromic properties of these compounds revealed that 1) the UV‐visible absorption spectra of the closed‐ring isomer were dependent of the element present in the N,N′‐chelating pocket and 2) incorporating the dithienylethene into a side‐functionalized phosphorane polymer greatly increased the closed‐/open‐ring reversibility and decreased the formation of by‐products.
