✦ Synopsis
Nickel‐catalysed Isomerization of Unsaturated Azocompounds
Unsaturated azocompounds, produced by the nickel‐catalysed reaction of butadiene with hydrazones, can be isomerized in presence of the same nickel catalyst. The influence of nickel concentration, temperature and structure of the azocompound on this rearrangement is described.

**Nickel‐catalysed Reaction of 2‐Aza‐1, 3‐butadienes with 1, 3‐Butadiene** The nickel‐catalysed reaction of butadiene with 2‐azabutadienes yields a mixture of 1 aza‐1,5,9‐cyclododecatrienes, __N__‐alkylidene‐divinylcyclohexylamines and open chained 2:1 adducts.
**Studies on the nickel‐catalysed reaction of butadiene with hydrazones** The nickel‐catalysed reaction of butadiene with methyl‐hydrazones yields a series of isomeric azo‐compounds identified as 2:1 adducts. The products are compared with those of the analogous reaction of butadiene with imines (c
