Abstract
A formal carbon insertion of acylsilanes into B–B and B–Si bonds has been developed. The in situ formed siloxycarbene under blue LED irradiation worked as the intermediate for the reaction. When 2-furyl and 2-thiophenyl acylsilanes were used, the B(pin) ring was enlarged to a six-membered ring.
