Abstract
We studied the influence of acetic acid concentration on the deaminati on and dephosphonylation of the adduct resulting of the nucleophilic r eaction between adequate alpha-metalated phosphonate and imminium salt , to enhance the yield of such reactions in order to access efficientl y a lot of unsymmetrical TTF derivatives. A mechanism is proposed for the formation of TTF, including steps, i(1) to i(7) The potential conc urrent formation of phosphonate (1) under bar and other by-products is also discussed (C) 1998 Published by Elsevier Science Ltd.
