Abstract

Phosphates and phosphoric amides were synthesized by the reaction of phosphoryl chloride with allyl alcohol, 2,3-dibromopropanol, 2-pyrrolidone and ethylenimine. All of these compounds were thermally very unstable. Allyl phosphorodichoridate and diallyl phosphorochloridate gave significant amount of polymeric products when they were distilled. IR spectra showed characteristic P=O stretching bands between 1300 and $1200 cm^{-1}$ and NMR spectra were very complicated due to the long range coupling effect of phosphorus atom. And mass spectrum of 2,3-dibromopropyl phosphorodichloridate gave no indication of molecular ion peak.

Phosphoryl chloride와 allyl alcohol, 2,3-dibromopropanol, 2-pyrrolidone, ethylenimine을 반응하여 여러가지 phosphate와 phospshoric amide를 합성하였다. 합성한 화합물은 모두 열에 불안정하였으며, allyl phosphorodichloridate와 diallyl phosphorochloridate는 증류하면 상당량의 중합체가 생겼다. IR 스펙트라에서는 $1,300∼1,200 cm^{-1}$에서 P=O stretching의 특성밴드가 나타났으며 NMR 스펙트라는 인원자의 long range coupling 효과로 인해 복잡한 피이크를 보였다. 2,3-dibromopropyl phosphordichloridate의 mass 스펙트럼에서는 분자이온 피이크를 볼 수 없었다.
