✦ Synopsis

We studied the influence of acetic acid concentration on the deamination and dephosphonylation of the adduct resulting of the nucleophilic reaction between adequate ot-metalated phosphonate and immlnium 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 TIT, including steps, i~ to i-. The potential concurrent formation of phosphonate 1 and other b)-products is also discussed.
