| In the reaction, it is clearly that ketones have better reaction activity than esters, and the coupling reaction yield of ketones is much higher than that of esters. Also, the substitutent species and the position on phenyl ring effects the reaction. In the crossing coupling reactions, the yield is at similar level due to unobvious electron effect resulted from the existence of ketones. |
