摘要：
Whereas the lithiated carbanion derived from the diethyl (N-allyl, N-phenyl)-amino methylphosphonate 1 failed to undergo the [2,3]-Wittig shift, ammonium salts resulting from the quaternization of diisopropyl (N,N-diethyl)-aminomethylphosphonate 8 with allylic bromides, were conveniently rearranged into the alpha-(N,N-diethylamino)-alkenylphosphonates 11, in the presence of t-BuOK, in DMF, at -40 degrees C.
