Summary
-
1.
As a result of the reaction between perfluorovinylmagnesium iodide and PCl3, AsCl3, and SbCl3, the corresponding tris-(trifluorovinyl)-phosphine, tris-(trifluorovinyl)-arsine, and tris-(trifluorovinyl)-stibine were obtained.
-
2.
Amides of the type ClP(NR2)2 reacted smoothly with R'MgX (where R' is alkyl or perfluoroalkenyl) to form substituted amides of the alkyl or perfluoroalkenyl phosphinic acids.
-
3.
Cleavage of amides of the type R'P(NR2)2 with dry hydrogen chloride led to the formation of primary and secondary chlorophosphines; in this way (C2H5)2PCl2, CF2=CFPCl2, (CF2=CF)2PCl were obtained. By exchange of chlorine with fluorine in the last two substances we obtained CF2=CFPF2 and (CF2=CF)2PF.
-
4.
The reaction of perfluorovinylmagnesium iodide with 10-chloro-5, 10-dihydrophenarsine gave 10-perfluorovinyl-5, 10-dihydrophenarsine, which was converted into perfluorovinyldichloroarsine in the quantitative yield by liquid hydrogen chloride.
