WebThe mechanism of our previously reported catalytic asymmetric bromocyclization reactions using 2,2′-bis (diphenylphosphino)-1,1′-binaphthyl (BINAP) monoxide was examined in detail by the means of control experiments, NMR studies, X-ray structure analysis, and CryoSpray electrospray ionization mass spectrometry (ESI-MS) analysis. WebJul 16, 2024 · Bisphosphine 2 exhibits ambidentate character in either the κ 2 -P,N or κ 2 -P,P coordination mode. Treatment of 2 with [M (CO) 4 (piperidine) 2] (M = Mo and W) yielded κ 2 -P,N and κ 2 -P,P coordinated Mo 0 and W 0 complexes [M (CO) 4 (2)] [M = W-κ 2 -P,N (4); Mo-κ 2 -P,P (5); W-κ 2 -P,P (6)] depending on the reaction conditions.
