Annulation of Metallabenzenes: From Osmabenzene to Osmabenzothiazole to Osmabenzoxazole

摘要

Research into transition-metal-containing metallaaromatics is attracting considerable current attention. Since the first example of metallabenzenes were reported by Roper et al. in 1982, a wide variety of monocyclic metallaaromatics have been successfully isolated and characterized. However, the chemistry of fused metallaaromatics is less developed.
