2-(芳氧基苯基硫代膦酰基)-1,2,3σ~2-二氮磷杂环戊二烯的合成

Synthesis of 2-(Aryloxyphenylthiophosphonyl)-1, 2, 3 σ~2-diazaphospholse

芳香氮磷杂五元环是环状二配位磷化合物中的一类,近年来已有综述报道。1,2,3σ~2-二氮磷杂环戊二烯首先由Ignatova提出。

A series of two-coordinate phosphorus compounds 2-(Aryloxyphenylthiophosphonyl)-1, 2, 3σ~2-Diazaphospholes (4) have been prepared by dehydrohalogenation of the 2-(Aryloxyphenylthiophosphonyl)-3-chlor-1, 2, 3-Diazaphospholine (3). They were synthesizedthrough the reaction of Aryloxyphenylthiophosphonylhydrazones (2) with PCl_3. The structuresof these new compounds have been confirmed by elemental analysis, IR, ~1H NMR, ^(31)P NMRand MS.
