Article abstract of DOI:10.1016/S0040-4039(00)79063-0

Dirhodium(II) tetra(triphenylacetate), Rh2(TPA)4, featured by a bulky bridging ligand has been demonstrated to exhibit an exceptionally high order of selectivity for C-H insertion into methylene over methine in catalytic decompositions of α-diazo β-keto e
