Experiments leading to the preparation of 3-methylenecyclobutanone are described. The desired substance was obtained only admixed with 3-methylcyclobutenone and this fact prevented evaluation of possible cross-ring π-type electronic interaction between the double bond and the carbonyl group.
描述了导致制备 3-亚甲基
环丁酮的实验。所需物质仅与
3-甲基环丁烯酮混合获得,这一事实妨碍了对双键和羰基之间可能的交叉环 π 型电子相互作用的评估。
