Bartlett实验室的结果21”· 0'3清楚地表明，途径1和途径2的机制细节可能有很大不同。对于下面的乙烯基醚，Bartlett及其同事倾向于[2+ 2]环加成途径3用于单线态氧反应（反应3），而两步途径21”· 0在直接反应（反应4）中具有长寿命的两性离子中间体。本文指出亚磷酸酯偶氮化合物与四甲基乙烯的直接反应与单线态氧的反应非常相似。
Results from Bartlett’s laboratory21”· 0'3 make it clear that the mechanistic details of pathways 1 and 2 can differ dramatically. With the vinyl ethers below, Bartlett and co-workers favor a [2+ 2] cycloaddition pathway3 for the singlet oxygen reaction (reaction 3) and a two-step pathway21”· 0 with a long-lived zwitterionic intermediate in the direct reaction (reaction 4). We point out in this communication that the direct reaction of phosphite ozo-nides with tetramethylethylenes is, in contrast, very similar to that of singlet oxygen.
