Critical influence of NHC ring size: highly labile [Ir(5-Mes)2(H)2]+can only be studied by trapping experiments, while [Ir(6-Mes)2(H)2]+and [Ir(6-Xyl)2(H)2]+are air/moisture stable.

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.
