Selective Synthesis of the Geometrical Isomers of<i>O</i>,<i>O</i>-Diethyl<i>O</i>-1-(<i>N</i>-methoxyimino)ethylphosphorothioate and a New Thiono-Thiolo Rearrangement Reaction
Condensation of O,O-diethyl phosphorochloridothioate with N-methoxyacetamide in the presence of a base gave selectively the geometricalisomers of O,O-diethyl O-1-(N-methoxyimino)ethylphosphorothioate which on heating rearranged to the corresponding thiolo isomers having P–S–C=N linkage.
在碱的存在下,O,O-二乙基硫代氯代磷酸酯与 N-甲氧基乙酰胺的缩合选择性地产生 O,O-二乙基 O-1-(N-甲氧基亚氨基)乙基硫代磷酸酯的几何异构体,其在加热时重排为相应的具有 P 的硫醇异构体–S–C=N 链接。
