This work discloses a strategy for the implementation of ON-ON organometallic catalytic processes using photoresponsive phosphine ligands. The approach leverages on the regiodivergent reactivity of mono- and bimetallic gold complexes that results from - vs -activations of alkynyl-substituted urea substrates, for the selective formation of eitherdihydroquinazolinone or indole-carboxamide products, via intramolecular hydroamidation.

Abstract
This work discloses a strategy for the implementation of ON-ON organometallic catalytic processes using photoresponsive phosphine ligands. The approach leverages on the regiodivergent reactivity of mono- and bimetallic gold complexes that results from - vs -activations of alkynyl-substituted urea substrates, for the selective formation of eitherdihydroquinazolinone or indole-carboxamide products, via intramolecular hydroamidation.
