Dirhodium (ii) carboxylate complexes as building blocks. cis-Chelating dicarboxylic acids designed to bridge the dinuclear coreElectronic supplementary information (ESI) available: Tables S1 and S2. See http://www.rsc.org/suppdata/nj/b3/b310008a/
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 obtained from diacids with methyl groups on the ether side arms and bulky substituents on the aromatic ring next to the ether links.
