An Efficient and Recyclable Catalyst for N??Alkylation of Amines and β??Alkylation of Secondary Alcohols with Primary Alcohols: SBA??15 Supported N??Heterocyclic …
Abstract A mesoporous silica (SBA-15)-supported pyrimidine-substituted N-heterocyclic carbene iridium complex was prepared and used as a catalyst for both environmentally friendly N-alkylation of amines and β-alkylation of secondary alcohols with primary alcohols. The structure of the supported iridium catalyst was characterized by Fourier transform infrared (FT-IR), 13 C and 29 Si solid-state nuclear magnetic resonance (NMR), small- ...
