Zinc-catalyzed transformation of diarylphosphoryl azides to diarylphosphate esters and amides

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%).

Copper catalyzed synthesis of aryl/alkyl mixed phosphates from diphenylphosphoryl azides and aliphatic alcohols under mild conditions

An efficient and convenient one-pot protocol is developed to prepare aryl/alkyl mixed phosphates in the presence of copper catalyst under exceptionally mild conditions. A series of versatile, ubiquitous, and inexpensive phosphoryl azides and aliphatic alcohols are combined for the first time ever. Diphenylphosphoryl azide is employed as novel phosphors reagent through an unexpected cleavage of P[sbnd]N bond. The transformation is advantageous with respect to a broad of functional group compatibility and different esterification products are isolated in good to excellent results. This new catalytic system represents a superior platform towards a mild, operationally simple, practical, and scalability alternative to access target molecules. Furthermore, a plausible mechanism is proposed based on insightful mechanistic studies.

Direct aerobic oxidative esterification and arylation of P(O)-OH compounds with alcohols and diaryliodonium triflates

Copper-catalyzed aerobic oxidative esterification of P(O)-OH compounds is achieved using alcohols as efficient esterification reagents, giving the expected products with good to moderate yields. Furthermore, it is shown that the arylation of P(O)-OH compounds proceeds efficiently to produce the corresponding products via the treatment of diaryliodonium triflates under mild reaction conditions. It is a simple way to produce a broad spectrum of functionalized phosphinates, phosphonates, and phosphates from basic starting materials with good to excellent yields. The protocol is convenient for practical application. A plausible mechanism has been proposed for the reaction.
