(α-Haloalkyl)phosphonium Salts and Sulfur Nucleophiles: A New Type of Reaction Mechanism
Galli, Remo
, p. 5349 - 5356 (2007/10/02)
Reaction between (α-haloalkyl)phosphonium salts and some sulfur nucleophiles leads to the substitution product Ph3P+CH2SRX-.Evidence is presented that this substitution is not a normal SN2 reaction and that it occurs through formation of a phosphonium ylide and a disulfide, reaction between them, and action of the resulting salt on the starting phosphonium salt.Then RSX and Ph3=CH2 reenter the sequence, giving rise to a three-step chain nucleophilic substitution.
