Phosphorylation with N-Phosphorylpyrazoles, IV. - Phosphorylations of Carboxylic Acids

Regitz, Manfred,Weise, Gisela,Felcht, Utz

, p. 1232 - 1238 (2007/10/02)

Reaction of 1-phosphorylpyrazole (1a) with the carboxylic acids 5a-f leads initially to the mixed anhydrides 6a-f, which then transform the 1-H-pyrazole 3, arising from phosphoryl group transfer, into the 1-acylpyrazoles 7a-f.Carboxylic acid phosphinic acid anhydrides 6b, c and g-k are also formed on reaction of the phosphinic acid chloride 9 and carboxylic acids in the presence of triethylamine; acylation of 3 with 6b, c, i and k is described.
