研究了嵌入聚氯乙烯 (PVC) 中的苯基取代的 C、N 和 S 杂环化合物在 10-15 K 下的光解作用。在每种情况下均形成了被认为是苯基噻嗪的化合物。它在 10–15 K 下稳定，加热时会重排为苯甲腈硫化物，在更高温度下又分解为苯甲腈和硫。
The photolysis of phenyl-substituted C-, N-, and S-containing heterocyclic compounds embedded in poly(vinyl chloride)(PVC) at 10–15 K has been studied. A compound believed to be phenylthiazirine was formed in each case. It is stable at 10–15 K, and on heating it rearranges to benzonitrile sulphide, which at still higher temperature decomposes to benzonitrile and sulphur.
