Abstract

Results Addition of an excess of alkene to 1 in CDC1, at 34 OC resulted in the formation of 2 and the corresponding oxiranes in moderate to high yields. Tetrasubstituted alkenes were found to be more reactive than trisubstituted alkenes. Disubstituted alkenes were found to be unreactive6 or only marginally reactive in the epoxidation reaction. Product yields were found to be dependent upon the concentration of the alkene. Addition of 1 equiv of alkene ...
