The reactions of fluorinated heterobutadienes F2C=X-C(R)=Y (X = N, CH; Y = O, N-Mes; R = Ph, t-Bu), A-D, with the PMe3 were studied. In any case, a different reaction pathway was observed, depending on the specific nature of A-D. These reactions lead to some novel organophosphorus species, including P-ylides and; lambda(5)-azaphosphinines.; lambda(5)-phospholenes, as observed with phosphites, for example, were not observed, but with phosphinidine (P-Ph), the heterobutadienes B and C form lambda(3)-oxazaphosphoknes. Therein the complex (Me3P)(3)Ni[cyclo-P(Ph)OC(Ph)NC(CF3)(2)] was obtained and structurally characterized.
