Bis(iodozincio)methane, prepared from lead-catalyzed reaction of zinc with diiodomethane, afforded 1,3-diketones either by the reaction with acyl cyanides or by palladium catalyzed reaction with acyl chlorides. Reaction with adipoyl dichloride gave cyclic enol ester by intramolecular reaction.
双(碘锌氧)甲烷(由铅催化的锌与二碘甲烷反应制备)通过与酰基氰化物反应或通过钯催化的与酰基氯反应,生成1,3-二酮。与己二酰二氯反应得到环状烯醇酯,这是通过分子内反应实现的。
