The Michael addition of lithio derivatives 2 of 1-(arylmethyl)benzotriazoles 1 to arylideneamines 3-5 gave the corresponding 1-(benzotriazol-1-yl)-2-anilino (or tosylamino)-1,2-diarylethanes 6-8.The latter were shown to undergo a double elimination reaction under the action of ButOK in DMF to afford diarylalkynes in high yields.
