Abstract: | (CF3)2EPH2 (E = P,As) may be prepared in high yield by the cleavage of M-P bonds in compounds of the type R3MPH2 (M = Si, Ge, Sn) with (CF3)2EX (X = Cl, Br, I). The direction of bond fission depends on X and on the reaction temperature. These new compounds may also be obtained, but in lower yield, by the reaction of LiAl(PH2)4 with (CF3)2EX. Application of the principle of this reaction to other R′2EX compounds (CH3)2PCl, (CH3)2AsI, F2PX (X = Br, I)] has been investigated. The IR and NMR spectra of the new compounds are reported. |
