异构的

The reaction proceeds through unstable intermediates such as the bipolar ion or peroxy radicals, which can isomerize or degrade, cause decomposition of macromolecules.

这一反应过程中，双极离子或过氧自由基等不稳定介质能引发异构或降解，从而导致高分子的分解。

The energy-rich intermediate anions, eg. [CH2＝C—OH]－ as the initial product of the insertion reaction and [CH2＝CHO]－ as the direct bonding product, are able to isomerize and decompose to various final products, such as C2H－＋H2O, CH2C＋OH－ and CH3－＋CO.

其中， 通过插入反应形成的富能中间体[CH2＝C—OH]－及键合中间体[CH2＝CHO]－都可以进一步经异构化和解离生成其它各种可能产物，如C2H－＋H2O， OH－＋CH2C和＋CO产物通道。
