Abstract
A diarylgermylene [Tbt(Tip)Ge:] kinetically stabilized by 2,4,6-tris-[ bis(trimethylsilyl)methyl]phenyl (Tbt) and 2,4,6-triisopropylphenyl (T ip) groups was allowed to react with phenyl isothiocyanate to afford a germanium-containing four-membered heterocycle, 4-imino-1,3,2-dithiag ermetane derivative via [2+2]-cycloaddition reaction of initially form ed diarylgermanethione [Tbt(Tip)Ge=S], the intermediacy of which was e videnced by electronic spetroscopy.
