摘要

Various N, N, N', N'-tetrasubstituted 1, l-diaminoethylenes (5) have been prepared by the reaction of N, N-disubstituted (trimethylsilylethyny1) amines (silylynamines 1, 2, and 3) with secondary amines. At 200" C in amine solvent, 5 afforded a mixture of [1, 3] alkyl rearrangement products (7) and dealkylation products (8 and/or 9).
