Under this reaction condition, several unsaturated carbonyl substrates give moderate to good chemical yield and shows good to excellent in diastereoselectivity. Two solvents were screened for some substrate and found that the chemical yield and diastereoselectivity is higher in toluene for a particular substrate. Interestingly the beta phenyl 2b, altogether gives different product in acetonitrile. For simple olefin substituent, the Diastereoselectivity is decreased from toluene to acetonitrile. In contrast to the reported method for simple cyclopropanation electron withdrawing group (ester) gives excellent yields in chemical (92 %) as well as diastereoselectivity (>99.5%). In general,  or substituents olefins give good diastereoselectivity, whereas simple olefin shows poor selectivity. However, despite its utility and simplicity, limitations are sometimes encountered, particularly with less reactive -dimethyl (2h) and -dimethyl (2i)
