Abstract:Abstract

The reactions of dihaloaminophosphines RNHPF2, (R=H, Me, tBu) and R2NPCl2 (R?Me, Et, SiMe3; R2?CH2(CH2CMe2)2 with LiOCH(CF3)2 yield the corresponding aminophosphites R2NPOCH(CF3)2)2. Hexafluoroacetone reacts with RNHOCH(CF3)2]2 as well as MeNHPF2 and tBuNHPF2 in good yields to the 1,3,5λ5-oxazaphosphetanes 1-4, which show rapid pseudorotation at room temperature.
