principal product of gas phase thermal decomposition of 2-methoxy-2,5,5-trimethyl-Δ3-1,3,4-oxadiazoline (methoxyoxa-diazoline) was found to be 1-methoxy-1-[(1-methylethenyl)oxy]-ethane (vinyl ether). This arises from a selective 1,4-hydrogen shift in the carbonyl ylide intermediate. Fragmentation of the carbonyl ylide is the dominant process in the solution thermolysis of methoxyoxadiazoline. The phase
发现 2-甲氧基-2,5,5-三甲基-Δ3-1,3,4-恶二唑啉(甲氧基恶-重唑啉)气相热分解的主要产物是 1-甲氧基-1-[(1-甲基乙烯基)氧基]-乙烷(乙烯基醚)。这是由羰基叶立德中间体的选择性 1,4-氢位移引起的。羰基叶立德的裂解是甲氧基恶二唑啉溶液热解的主要过程。根据羰基叶立德中间体的可能结构讨论了这种热解的相和温度依赖性。
