    摘要: New unsaturated 1,2-diazacyclododecanes, more particularly 1,2-diazacyclododecatrienes-1,5,9 and 1,2-diazacyclododecanes-1 and a novel process for the preparation thereof are disclosed which process comprises reacting a 1,3-diolefin with an azine in the presence of certain nickel catalysts. Said process unexpectedly yields 12-membered ring compounds only, and more especially oligomerization products of 2 mols of a 1,3-diolefin and 1 mol of an azine, while deactivation of the nickel catalyst by the -N=N-bond is avoided.
