Solid-supported catalysts derived from homogeneous nickel(ii) and palladium(ii) non-symmetrical salen-type coordination complexes have been prepared and shown to be effective in the heterogeneous catalysis of carbonâ carbon cross-coupling reactions. The nickel catalyst has been used in room-temperature Tamaoâ Kumadaâ Corriu reactions and the palladium catalyst in the Heck reaction at elevated temperatures. The complexes were prepared by improved methods and characterised by spectroscopic techniques. Comparisons between the solid-supported catalysts and their homogeneous analogues are reported. The single-crystal structure determination of the nickel and palladium complexes [M(salenac-OH)] [M = Ni, Pd; salenac-OH = 9-(2â ²,4â ²-dihydroxyphenyl)-5,8-diaza-4-methylnona-2,4,8-trienato](2â )] is reported.
