Abstract

In contrast to the successful formation of germaniumsulfur double-bond compounds by the reactions of thermodynamically stabilized germylene with elemental sulfur, 2 only 1, 2, 3, 4, 5-tetrathiastannolane 5 6 3 9 was isolated (9%) as a sulfurized product upon treatment of stannylene 2a with elemental sulfur (Scheme I). On the other hand, when the deep purple solution of Za in hexane was treated with styrene episulfide at room temperature, the ...
