Facile synthesis of dimeric BODIPY and its catalytic activity for sulfide oxidation under visible light

Abstract

An orthogonal dimeric BODIPY was easily prepared via condensation of 2,4-dimethylpyrrole and oxalyl dichloride, and was utilized as a visible-light-driven photocatalyst for the oxidation of sulfides. High catalytic efficiencies, and mild and green conditions are the major advantages of this protocol. Moreover, meso-carbalkoxylated BODIPYs could also be prepared using a similar one-pot condensation of 2,4-dimethylpyrrole, oxalyl dichloride and a series of alcohols.
