Abstract Application of the extended Grunwald-Winstein equation to the solvolyses of phenyl 4-methylphenoxy thiophosphinyl chloride (1) led to 1.08±0.08 for l, 0.53±0.03 for m, and 0.19 for c; the R value was 0.958. The l and m values for the solvolysis of 1 were compared with recently reported results for the specific rates of solvolysis of diphenyl thiophosphorochloridate, diphenyl phosphorochloridate, and diphenylphosphinyl chloride. The l value of 1.08 and the m value of 0.53 for the solvolysis of 1 were consistent with the reported works which indicates a SN2 mechanism involving an attack by the solvent at phosphorus of 1.
