Carboxylation of alkylboranes by N-heterocyclic carbene copper catalysts: Synthesis of carboxylic acids from terminal alkenes and carbon dioxide

Caught in the act: N-Heterocyclic carbene copper(I) complexes (1; IPr=1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) serve as an excellent catalyst for the carboxylation of alkylboranes (2; R=alkyl) with CO2 to afford a variety of functionalized carboxylic acids (3) in high yields. A novel copper methoxide/alkylborane adduct (A) and its subsequent CO2 insertion product (B) have been isolated and shown to be true active catalyst species.

Photoinitiators for photopolymerization of unsaturated systems

Compounds of the general formula I STR1 wherein Z is CR1 R2 (OR3) or phenyl, R1 being H, C1-6 -alkyl or phenyl, R2 being H, C1-6 -alkyl or C1-6 -alkoxy and R3 being H, C1-6 -alkyl or C1-6 -alkanoyl and Z' is Y--[(CH2)m --X]n --, X being CH2 or 0, Y being OH; COOH or SO3 H including the alkali metal, alkaline earth metal or ammonium salts thereof and also the salts thereof with organic nitrogen bases; or NRR' in which R and R' are in each case H, C1-20 -alkyl or C1-4 -hydroxyalkyl, if appropriate quaternized or in the form of the acid addition salts, and n and m each being the numbers 1-4, are excellently suitable as photoinitiators for the photopolymerization of ethylenically unsaturated compounds, in particular in aqueous systems.

Liquid Crystalline Properties of Cholesteryl ω-Arylalkanoates

The thermal properties of the homologous series of cholesteryl ω-(4-benzoylphenyl)- (I), ω-(4-benzylphenyl)- (II), ω-benzoyl- (III), and ω-phenoxyalkanoate (IV) have been investigated.For series I and II the cholesteric-isotropic (Ch-I) transition temperatures, enthalpies, and entropies show a remarkable alternation.For series III and IV, the transition temperatures, enthalpies, and entropies exhibit weak alternation and their trends are opposite to those for series I and II, and the cholesteryl ω-phenylalkanoates.The cholesteric-isotropic transition temperatures are discussed in terms of the geometrical and electrical alternations stemming from the terminal aryl groups, and also the relative importance between these two terms.
