Organische Phosphorverbindungen. XI. Arylierung von PSCl 3 in Gegenwart von Friedel‐Crafts‐Aktivatoren. Ein neues Verfahren zur Darstellung von Thiophosphoäure‐dihalogeniden, Thiophosphinsäurehalogeniden und tertiären Phosphinsulfiden

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, RPSX 2 , (R=C 6 H 5 , ClC 6 H 4 , FC 6 H 4 , CH 3 , C 6 H 4 ; X=C1, Br), thiophosphinic halides, RR′PSCl (R, R′ =C 6 H 5 , ClC 6 H 4 , FC 6 H 4 , CH 3 C 6 H 4 , C 6 H 13 , C 6 H 3 CH 3 ; R =C 6 H 5 , R′=CH,; X = C1, Br), as well as of tertiary phosphine sulfides, RR′R″S (R, R′R″= C 6 H 5 , ClC 6 H 4 , CH 3 C 6 H 4 , C 6 H 13 , C 6 H 3 CH 3 ; R =CH 3 , R′R″=C 6 H 5 , and R =CH 3 , R′=C 2 H 5 , R″=C 6 H 6 ) is described. Some reactions of tertiary phosphine sulfides are also reported.
