A versatile synthetic route to 1-benzometalloles involving the first examples of several C-unsubstituted benzometalloles
Abstract
The group 14 (Si, Ge, Sn), group 15 (P, As, Sb, Bi) and group 16 (S, Se, Te)(2-trimethylsilyl)-1-benzometalloles 5 have been prepared from phenylacetylene via three steps and converted into the corresponding C-unsubstituted benzometalloles 7 by detrimethylsilylation.
