divergent synthesis of chromones and chromanones from a common substrate via reductive coupling cyclization by switching hydrosilanes has been developed. Results of mechanistic studies revealed that under PhMeSiH conditions, the reaction initially undergone cyclization to form chromones , which can subsequently be reduced to yield chromanones . When the hydrosilane was switched to EtSiH, the reaction route
