OLEFINATION OF KETONES USING 1,1-DIMETALLOALKANES DERIVED FROM i-Bu2AlCH=CHR - Cl2TiCp2 SYSTEM

The alkylidenation of ketone carbonyls using 1,1-dimetalloalkanes prepared by the reaction of 1-alkenyldiisobutylalanes with titanocene dichloride afforded the corresponding olefins in good yields.

Alkene homologation: via visible light promoted hydrophosphination using triphenylphosphonium triflate

A hydrophosphination reaction of alkenes with triphenylphosphonium triflate under photocatalytic conditions is described. The reaction is promoted by naphthalene-fused N-acylbenzimidazole and is believed to proceed through intermediate formation of a phosphinyl radical cation. The resulting phosphonium salts are directly involved in the Wittig reaction leading to homologated alkenes.

Ruthenium(II)-catalyzed olefination: Via carbonyl reductive cross-coupling

Natural availability of carbonyl groups offers reductive carbonyl coupling tremendous synthetic potential for efficient olefin synthesis, yet the catalytic carbonyl cross-coupling remains largely elusive. We report herein such a reaction, mediated by hydrazine under ruthenium(ii) catalysis. This method enables facile and selective cross-couplings of two unsymmetrical carbonyl compounds in either an intermolecular or intramolecular fashion. Moreover, this chemistry accommodates a variety of substrates, proceeds under mild reaction conditions with good functional group tolerance, and generates stoichiometric benign byproducts. Importantly, the coexistence of KOtBu and bidentate phosphine dmpe is vital to this transformation.
