In order to investigate the reaction mechanism of intramolecular C-H insertion by Rh(Ⅱ)-mediated carbenoids with rrans-(2-phenylcyclopropyl)carbinal radical as the mechanistic probe, diazo compounds 2-(2-phenylcyclopropyl)ethyl diazoacetoacetate 8a and methyl 2-diazo-3-oxo-6-(2-phenylcyclopropyl)hexanoate 8b have been synthesized. Preliminary investigation of the intramolecular C-H insertion with Rh₂(OAc)₄ as catalyst supports a concerted insertion process.
