摘要：

The reaction of an MeLi/HMPA mixture in ether with dimesityl- and mesitylphenylketene yielded the enols MesC(Ar) = C(OH)PO(NMe2)2 and MesC(Ar) = CHOH and the amides MesCH(Ar)CON(Me)R (Ar = Mes, Ph; R = Me, Et) together with other products. An initial cleavage of the HMPA by the MeLi, followed by addition of the formed anionic species (Me2N)2PO-, Me2N-, or MeN-Et to the diarylketene, is proposed.
