Irradiation at 254 nm of P-NMe2 and P-OEt derivatives of phosphonates where P is incorporated into the 2,3-oxaphosphabicyclo[2.2.2]oct-5-ene framework results in fragmentation of the molecules to release N,N-dimethylamino metaphosphoramidate and ethyl metaphosphate, respectively. Both species polymerize rapidly, but are effectively trapped as phosphate deriva- tives when alcohols are included in the
在254 nm处照射P-NMe 2和P-OEt膦酸酯衍生物,其中P掺入2,3-氧杂磷双环[2.2.2] oct-5-ene骨架中,导致分子断裂,释放N,N-二甲基氨基偏氨基磷酸酯和偏磷酸乙酯。两种物质都迅速聚合,但是当反应混合物中包含醇时,它们会有效地被捕获为磷酸盐衍生物。
