Thermal rearrangements of 3-dimethylaminohex-5-en-1-ynes (5) yield biphenyls (6).The mechanism of the transformation (5) -> (6) involves a sequence of (i) a sigmatropic rearrangement, (ii) a hydrogen shift, (iii) an electrocyclic reaction, and (iv) elimination of dimethylamine (Scheme 2).

Base-catalysed rearrangement of the salts (I) in aprotic media gives the amines (II) and (III); the amines (II) on heating yield the biphenyl derivatives (V).
