Rhodium-catalyzed tandem cyclization/Si-C activation reaction for the synthesis of siloles.
Siloles represent an important emerging class of photoluminescent materials. Reported herein is a new synthetic strategy involving a tandem cyclization/Si-C activation reaction featuring high efficiency, wide substrate scope, and practical utility. This method enabled the first synthesis of benzofuran siloles as well as rapid access to conjugated siloles. During the course of the study we also uncovered an unusual yet general Si-C(sp(2)) activation in the presence of π acids.
