Abstract

Abstract A new type of palladium (0) complex,(5, 8-dihydro-1, 4-naphthoquinone) Pd (PPh 3) 2 and (5, 8, 9, 10-tetrahydro-1, 4-naphthoquinone) Pd (PPh 3) 2, having both olefin and quinone or dihydro-quinone sites in a ligand molecule was prepared. IR and 1 H NMR spectroscopic studies of these complexes suggested that it is the quinone or dihydro- quinone C C bond which is complexed to Pd. Ligand exchange reactions showed that ...
