versatile and environmentally friendly synthetic method for the formation of acylphosphates is reported. By employing electrochemical oxidative dehydrogenative coupling, this transformation features a broad range of substrates, as well as metal-free, oxidant-free and mild conditions. One-pot synthesis of amides from acylphosphates with amines was accomplished with high efficiency and regioselectivity,

The Pd-catalyzed cross-coupling reactions of carboxylic phosphoric anhydrides with organoboronic acids or organostannanes afforded the corresponding ketones. The intramolecular Heck reaction was successful with carboxylic phosphoric anhydrides as a coupling partner.
Carboxylic‐Phosphoric Anhydrides as Direct Electrophiles for Decarbonylative Hirao Cross‐Coupling of Carboxylic Acids: DFT Investigation of Mechanistic Pathway
of decarbonylative Hirao cross-coupling of carboxylic-phosphoric anhydrides (acyl phosphates) to afford aryl phosphonates. Direct dehydrogenative decarbonylative phosphorylation of benzoic acid can be performed in high yield via decarbonylative coupling in the presence of phosphite as dual activating and nucleophilic reagent. DFT studies were conducted to gain insight into this decarbonylative process

selective C(O)–O bondcleavage. Carboxylic–phosphoric anhydrides are highly active carboxylic acid derivatives, which are generated throughactivating carboxylic acids using phosphates by esterification or direct dehydrogenative coupling with phosphites. Highly valuable internal alkynes have been generated by the present method, and the efficiency of this approach has been demonstrated through a wide
