Preparation method of phosphinate, phosphinate and non-aqueous electrolyte

The present invention provides a method for preparing phosphinate, the phosphinate and a non-aqueous electrolyte. The method for preparing the phosphinate comprises the following steps: (1) reaction of Grignard reagent R1MgX with thiophosphoryl halide X3P=S in a solvent to obtain a first intermediate; (2) reaction of halogenating agent M' Xa and the first intermediate to obtian a second intermediate; and (3) reaction of the second intermediate with R2OH and water to obtain the phosphinate; wherein R1 and R2 are each selected from the group consisting of hydrocarbon groups or an organic group containing at least one element of boron, silicon, nitrogen, phosphorus, oxygen, sulfur, fluorine, chlorine, bromine, and iodine; X represents a halogen; M' represents a metal element; and a representsa valence of the metal element M'. The electrolyte prepared by from the phosphinate can improve the high-temperature cycle stability of a secondary battery, also has non-flammable, flame-retardant orself-extinguishing characteristics, and can improve the safety performance of the secondary battery.

SYNTHESIS OF CYTIDINE DIPHOSPHATE-D-QUINOVOSE

The title molecule, cytidine-D-quinovose (CDP-6-deoxy-D-glucose) 1, was synthesized by two different methods from the key intermediate quinovose-1-phosphate 7 which was prepared from glucose.
