WebJul 1, 2015 · Recently, we developed the Ir (III)-catalyzed direct C (sp 2)–H amidation of arylphosphoryl compounds using organic azides as the amino source.13 Under the optimized conditions, diarylphosphoryl compounds (RAr 2 P O, R≠Ar) were readily amidated in excellent yields as a racemic mixture ( Scheme 2, in case of R≠Ph). WebWe 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 … biscuit white gravy recipe
