Abstract
Palladium catalysts, methods of synthesizing palladium-carbene catalysts, and methods of producing chromones and aurones using palladium-N-heterocyclic carbene (NHC) catalysts are provided. In some implementations, the palladium catalysts include a bridged palladium catalyst with distorted square planar geometry around the center palladium atom. The catalysts can be used in cyclocarbonylative Sonogashira cross-coupling reactions to produce chromones and aurones at a high yield. The selectivity of the catalysts can be adjusted by adjusting reaction conditions.
