A palladium-catalyzed, three-component reaction between propargylic alcohols, CO2, and aryl halides was developed whereby a sequential carboxylation, trans-oxopalladation of the C equivalent to C bond by an ArPdX species, and a reductive elimination procedure afforded a series of functionalized alpha-alkylidene cyclic carbonates in moderate to excellent yields. Notably, the configuration of these tetrasubstituted olefins was dominated by the trans-oxopalladation step where the aryl group derived from ArX is located trans to the oxygen attached in the double bond: This protocol features simultaneous formation of four novel bonds in a one-pot reaction, representing an efficient method for incorporation of CO2, into heterocycles.
