Title
Homogeneous and silica-supported azidoproazaphosphatranes as efficient catalysts for the synthesis of substituted coumarins
Abstract

Homogeneous and silica-supported azidoproazaphosphatranes derived from the Verkade's superbase catalyze the synthesis of substituted coumarins with moderate to good yields and high selectivity.
