We have developed a facile and efficient procedure for the synthesis of diarylphosphate esters and amides. Using Zn(acac)2 as the catalyst, the reaction of diarylphosphoryl azides with aliphatic alcohols and phenols through an unusual P?N bond cleavage provided a number of diarylphosphate esters in good yields (22 examples, up to 94%). Additionally, various diarylphosphate amides were obtained from the corresponding amines in excellent yields as well (8 examples, up to 96%).

Paragraph 0061-0065, (2019/10/17)
The invention provides a synthesis method of a copper-catalyzed phosphate mixed ester compound. The synthesis method comprises the steps that a phosphate ester azide compound and fatty alcohol are mixed, then a copper catalyst is added, alkali is added, reaction is conducted at the temperature of 20-100 DEG C for 3-24 h, and the phosphate mixed ester compound is obtained through aftertreatment. According to the synthesis method, the phosphate ester azide compound and the fatty alcohol are adopted to synthesize the phosphate mixed ester compound for the first time, in the synthesis process, only the copper catalyst and the alkali with the catalytic dosage are needed to be added, operation is easy, the defect of needing inert gas protection is overcome, and the synthesis method is novel andefficient.
