Abstract

The reactions of FâCP = CFâ (1) with MeâGeH, MeâSnH, and (CâRâ)(CO)âMH (M = Cr. Mo, W; R = H , Me) proceed via addition to the PC double bond yielding tertiary phosphanes of the type MeâMâ2P(CFâ)CFâH[Mâ2 = Ge (2), Sn (3)] or (CâRâ)(CO)âMP(CFâ)CFâH [R = H; M - Cr (6), Mo (7). W (8); R = Me; M = Mo (9), W (10)]. 2 and 3 are labile compounds, which decompose by elimination of MeâMâ2F , a reaction which in the case of 3 has been used to prepare the new phosphaalkene FâCP = C(H)F (5) and its [2+4]-cycloaddition product 4 with 2.3-dimethyl-1.3- butadiene. The H substituent (instead of F) in 5 and its derivatives has a surprising influence not only on the stability of the compounds but also on their spectroscopic data, as shown by com parison with 1 and derivatives of the type MeâM â2P(CFâ)â and (CâHâ)(CO)âMP(CFâ)â. respectively. New compounds are characterized by NMR, MS. GC/MS and IR measurements.
