摘要
Reaction of complex [Cp*Ir-(HOC5H3CH2C5H3OH)Cl][Cl] (1) with AgOTf generated the product [Cp*Ir(HOC5H3CH2C5H3OH)(H2O)][OTf](2) (2), which was further transformed to the complex [Cp*Ir-(OC5H3CH2C5H3O)(H2O)] (3) in the presence of t-BuONa via OH deprotonation. Complexes 1-3 exhibited high activity for the methylation of amines and ketones. These C-C and C-N coupling reactions proceeded in air with 1 mol % catalyst loading in the presence of K2CO3.
