Abstract
Miwed phosphorus-carboxylic anhydrides have demonstrated both acylating and phosphorylating properties.[1] Here we report the reactivity of O,O-diethyl(O-2,4,6-trimethylbenzoyl) phosphates (1), and O-methyl (O-2,4,6-trimetyIbenzoyl) dimethylphosphonates (2)with nucleophiles in the presence of different strong organic bases (DBU, DMAP).
