Copper-catalyzed oxidative C–H silylation of BODIPY dyes at the 2- or 2,6-positions with silanes

Abstract

A novel method has been developed for synthesizing silylated BODIPY derivatives through copper-catalyzed oxidative C–H silylation of BODIPYs with silanes. This approach exhibits good substrate compatibility and high regioselectivity, enabling access to a variety of β-silylated BODIPY fluorophores under mild conditions. Most of the resulting dyes demonstrate strong solid-state emission, attributed to the incorporation of bulky triphenylsilyl groups on the BODIPY core.
