摘要

Abstract A new series of calix [4] arene supported N-heterocyclic carbene palladium complexes were developed and fully characterized. A mono-substituted calix [4] arene was prepared through conventional procedures, following with the attachment of imidazolyl derivative groups to compose the precursors of novel NHCs ligands. Undergoing the alkylation with n-butylbromide and corresponding metallation with palladium and pyridine, ...
