Via thermolysis of bismuth sulfinates

Via thermolysis of bismuth sulfinates (method L) Thermolysis of bismuth tris(arenesulfinate), which can be prepared from bismuth acetate and arenesulfinic acid in glacial acetic acid, leads to the formation of triarylbismuthines [72AJC2107]. 

Bismuth tris(4-methylbenzenesulfinate) (ca. 0.1-0.2 g) was heated in a sublimation apparatus at 200°C/10 -10 mmHg. After 5 h, the crude sublimed product was collected and recrystal-
