Synthesis, structure, and some reactivities of kinetically stabilized plumb
ylenes are described. The reaction of an extremely hindered plumbylene Tbt(
2)Pb: (Tbt= 2,4,6-tris[bis(trimethylsilyl)methyl]pheyl with elemental sulfu
r gave Tbt(TbtS)Pb: via an interesting 1,2-aryl migration of the intermedia
ry plumbanethione, Tbt(2)Pb=S. The reactions of overcrowded aryl(arylthio)p
lumbylenes and bis(arylthio)-plumbylenes with carbon disulfide are also des
cribed.
