Abstract
The results of the reaction of 19 different halomethylphosphonium hali des, [R3PCYnX3-n]X (R = Ph, n-Bu, Me2N, Et2N; Y = H, F; X = Cl, Br, 1; n = 0-2), with Ph3P, n-Bu3P, and (R2N)3P are presented. As reaction p roducts bisphosphonium salts, [R3P-CYnX2-n-PR3]X2, and phosphoranylpho sphonium salts, [R3P = CY-PR3']X, or reduced (halo)methylphosphonium s alts, [R3PCHynX2-n]X, are obtained. [Ph3PCBrF2]Br and [BU3PCBrF2]Br re act with R3'P by transalkylation forming [R3'CBrF2]Br. The factors inf luencing the course of the reaction are discussed.
