Abstract

We studied the influence of acetic acid concentration on the deamination and dephosphonylation of the adduct resulting of the nucleophilic reaction between adequate α- metalated phosphonate and imminium salt. to enhance the yield of such reactions in order to access efficiently a lot of unsymmetrical TTF derivatives. A mechanism is proposed for the formation of TTF, including steps, i1 to i-. The potential concurrent formation of ...
