Mizoroki-Heck reaction of unstrained aryl ketone with acrylate/styrene is accomplished via palladium-catalyzed ligand-promoted C-C bond cleavage. Various (hetero)aryl ketones are compatible in the reaction, affording the alkene product in good to excellent yields. Further applications in the late-stage olefination of some drugs, natural products, and fragrance-derived aryl ketones demonstrate the synthetic utility of this protocol. By employing ketone as both the directing group and the leaving group, 1,2-bifunctionalization is achieved via sequential ortho-C-H alkylation/ipso-Heck olefination.

A series of esters of cholesterol with the cis,trans isomers of unsaturated monocarboxylic acids were synthesized.The effect of the nature and of the configuration of the substituents in relation to the double bond in the acid component of the cholesterol esters on the mesogenic capacity was established.The phase transition temperatures were determined.
