Abstract: a-and y-deuterium rate effects on the solvolysis of (1-methylcyclohexyl) methyl,(1- methylcyclopentyl) methyl, and (1-methylcyclobutyl) methyl sulfonate esters have been measured and the solvolysis products examined by* H NMR spectroscopy. The results indicate that the products of the solvolysis of all these sulfonate esters are predominantly (298%) rearranged. In the solvolysis of (1-methylcyclohexyl) methyl triflate, rearranged ...
