Abstract

A number of 2, 3-disubstituted 1-indenones have been prepared in fair to good yields by treating o-iodo-or o-bromobenzaldehyde withvarious internal alkynes in the presence of a palladium catalyst. Synthetically, the methodology provides an especially convenient route to stable hindered indenones containing aryl, silyl, and tert-alkyl groups. The reaction is believed to proceed through a palladium-(IV) intermediate, and the regiochemistry of the ...
