Palladium-Catalyzed Formal Hydroalkylation of Aryl-Substituted Alkynes with Hydrazones

We have developed an unprecedented Pd-catalyzed formal hydroalkylation of alkynes with hydrazones, which are generated in situ from naturally abundant aldehydes, as both alkylation reagents and hydrogen donors. The hydroalkylation proceeds with high regio- and stereoselectivity to form (Z)-alkenes, which are more difficult to generate compared to (E)-alkenes. The reaction is compatible with a wide range of functional groups, including hydroxy, ester, ketone, nitrile, boronic ester, amine, and halide groups. Furthermore, late-stage modifications of natural products and pharmaceutical derivatives exemplify its unique chemoselectivity, regioselectivity, and synthetic applicability. Mechanistic studies indicate the possible involvement of Pd-hydride intermediates.

Mechanistic switch via subtle ligand modulation: Palladium-catalyzed synthesis of α,β-substituted styrenes via C-H bond functionalization

A new catalyst system able to efficiently perform the synthesis of styrenes via C-H bond functionalization and a subtle ligand modification are described. The high level of activity achieved allows for the synthesis of highly functionalized α,β-substituted styrenes, even the elusive E-configured trisubstituted olefins, in a regio- and stereoselective manner. Mechanistic experiments allowed for the identification of the corresponding synthetic intermediates.

A novel and efficient method for the olefination of carbonyl compounds with Grignard reagents in the presence of diethyl phosphite

The widely available carbonyl compounds react with Grignard reagents in the presence of diethyl phosphite to give the corresponding olefins in good to excellent yields: A range of conjugated dienes, terminal olefins, multisubstituted-alkenes and conjugated enynes could be readily obtained by the method in mild conditions.
