The hydrogen coverage and the structures of the reactants influence the selectivity and mechanism of the ring-opening reactions of ethyl-(ECP), cis-1,2-dimethyl-(cDMCP), trans1,2-dimethyl-(tDMCP), 1,1-dimethyl-(1, 1DMCP) and 1, 1, 2, 2-tetramethylcyclopropane (TMCP) over Rh/SiO2 catalyst; a new phenomenon was observed for the transformations of ECP, tDMCP and 1, 1DMCP, viz. the turnover frequency vs. H2 pressure functions pass through a minimum.
