Direct synthesis of N-phosphanyl-heterocyclic carbenes
摘要:
A direct method for the synthesis of N-phosphanyl-heterocyclic carbenes is described. The method is based on the reaction of lithium imidazolides and benzimidazolides having a bulky alkyl group at the nitrogen atom with di(tert-butyl)chlorophosphine leading directly to the carbenes.
