High-efficiency green preparation method of thio-organic phosphonic acid derivative
-
Paragraph 0098-0101, (2020/09/23)
The invention discloses a high-efficiency green preparation method of a thio-organic phosphonic acid derivative. The thio-organic phosphonic acid derivative is directly prepared by reaction of a P (O)-H compound, sulfur powder and alcohol, the reaction temperature is 80-120 DEG C, and the reaction time is 12-48 hours. According to the method, alcohol and sulfur powder which are stable, easy to obtain, low in price and relatively green can be directly used as raw materials, the P (O)-H compound can be directly used without any activation treatment, and the P (O)-H compound, sulfur powder and alcohol can directly react under the one-pot condition to efficiently prepare the thio-organic phosphonic acid derivative without any transition metal or non-metal catalyst and an additive. The method has the advantages of low requirements on reaction conditions, simplicity and feasibility in operation, no need of inert gas protection, water as a byproduct and small green pollution, and has high academic value and potential wide application prospect due to the wide application of the thio-organic phosphonic acid derivative in the fields of pesticides, medicines, materials and the like.
