Bis(trimethylsilyl)acetamide reacts with an equimolar proportion of PF2Br at -80 deg C to give CH3C(OSiMe3):NPF2.With an excess of PF2Br, the initial product at -80 deg C is CH3C(OPF2):NPF2; at temperatures above -40 deg C there is a slow rearrangement to give a mixture of CH3C(OPF2):NPF2 and CH3CON(PF2)2.All these PF2 derivatives of acetamide decompose slowly at room temperature to give acetonitrile and either PF2OSiMe3 or (PF2)2O.They have been characterised by 1H, 19F, and 31P n.m.r. and by i.r. spectroscopy.There was no evidence for fast exchange of PF2 groups between N and O sites.
