1λ3,3λ3-Diphosphanes of the type R2PCF2P(H)CF3 are formed in acceptable yields (40 - 75percent) by reacting perfluoro-2-phosphapropene F3CP=CF2 (1) with the corresponding secondary phosphanes R2PH.By reaction with sulfur, compounds 3, 5 and 7 selectively yield the corresponding monosulfur derivatives R2P(S)CF2P(H)CF3 .Treatment of 3 or 7 with dimethylamine (molar ratio 1/2) leads via HF elimination and addition of Me2NH to the aminophosphanes R2PCHFP(NMe2)CF3 .In a similar procedure HF has been eliminated from 3 by 1,4-diazabicyclooctan e (DABCO), and on addition of methanol or ethanol to the 1,3-diphosphapropene intermediate, the alkoxy compounds Me2PCHFP(OR)CF3 have been obtained.
