The reaction of benzene, toluene, chlorobcnzene, trimethoxybenzene, hexyl‐ toluene, methyl p‐anisate, thiophene, and furfurol with thiophosphorus trihalides, thiophosphonic dichlorides and thiophosphinic chlorides in the presence of FRIEDEL CRAFTS activators has been studied. The preparation of thiophosphonic dihalides, RPSX2, (R=C6H5, ClC6H4, FC6H4, CH3, C6H4; X=C1, Br), thiophosphinic halides, RR′PSCl (R, R′ =C6H5, ClC6H4, FC6H4, CH3C6H4, C6H13, C6H3CH3; R =C6H5, R′=CH,; X = C1, Br), as well as of tertiary phosphine sulfides, RR′R″S (R, R′R″= C6H5, ClC6H4, CH3C6H4, C6H13, C6H3CH3; R =CH3, R′R″=C6H5, and R =CH3, R′=C2H5, R″=C6H6) is described. Some reactions of tertiary phosphine sulfides are also reported.
