Pentafluorophenyl carbonyl compounds in the Reformatsky-type reactions promoted with Fe(CO)5-based metal complex systems
Iron pentacarbonyl is an effective promoter for additions of halogenated acid esters and nitriles to pentafluorophenyl carbonyl compounds 1, 4, and 5 by the Reformatsky-type reaction and reductive coupling of compound 1. The electron-withdrawing character
