Ph2P-PF2Ph2 has been identified by means 19F- and 31P- NMR spectroscopy as an intermediate product of the disproportionation of Ph2PF. The disproportionation is catalyzed by acids. The reaction mechanism is discussed. PhPF2 disproportionates faster in solution in acetonitrile than neat, forming (PhP)6, instead of (PhP)5.
Ph 2 P-PF 2 Ph 2已通过19 F-和31 P-NMR光谱法鉴定为Ph 2 PF歧化的中间产物。歧化是由酸催化的。讨论了反应机理。PhPF 2在
乙腈溶液中的歧化速度要快于纯净的,形成(PhP)6而不是(PhP)5。
