C–C bond cleavage is achieved with silver carbene species under relatively mild conditions (80 °C) stoichiometrically, and aldol condensation is catalyzed at ambient temperatures in high efficiency, with turnover numbers up to 5000 h−1, thus disclosing new applications and synthetic opportunities based on easily accessible silver carbene complexes.

Palladium Catalyzed

Under very mild conditions, functionalized benzoxaborole derivatives were prepared in good to excellent yields via a palladium-catalyzed Miyaura borylation reaction of readily available unprotected o-bromobenzylalcohols, and bis(pinacolato)diboron (B2pin2) without the assistance of an acid.
