Dirhodium(II) tetra(triphenylacetate): A highly efficient catalyst for the site-selective intramolecular C-H insertion reactions of α-Diazo β-Keto Esters
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-ketoesters tethered to a cyclic system, thus providing an expedient and geneal entry to bicyclic compounds in preference to spirocyclic compounds. The efficiency is verified well by high-yield and site-controlled
