- 中文摘要: Reaction of 3-azidopropyl methanesulfonate with triphenylphosphine produced the 1,4-bis(triphenyl-phosphino) piperazine (5) by intermolecular cyclization, instead of formation azidine derivatives by an intramolecular pathway. Structural formulation of (5) was achieved by both spectral and X-ray crystal analysis. Hydrolysis of (5) under basic condition gives piperazine, whereas reaction of lithium diphenylphosphide with (5) produced 1,2-bis(diphenyl- phosphino)ethane (dppe) exclusively.
