Abstract

The syntheses and crystal structures of a series of dicarboxylic acids of general structure HO2CCR2OArOCR2CO2H (LH2) designed to span a pair of cis sites on the dirhodium (II) tetracarboxylate framework are described. Monochelate complexes LRh2 (OAc) 2 and bischelate complexes L2Rh2 were prepared by heating the diacids with Rh2 (OAc) 4 in N, N- dimethylaniline. Chelates were formed under kinetic control and the best yields were ...
