Hydrogenation of nitrobenzenes bearing aldehyde-containing substituents over heterogeneous platinum or palladium catalysts gives medium and/or large heterocyclic amines as a result of simple or dimeric cyclisation in moderate to good yields; a range of heteroatoms can be incorporated into the macrocycles, enhancing their potential as ligands.

corresponding alkenes have been hydrogenated over heterogeneous palladium or platinum catalysts to give medium and large heterocycles either resulting from direct cyclisation or by the formation of dimers. The yields of monomers and dimers are discussed as a function of ring size and the pattern of heteroatom substitution in the substrates; in general the greater the number of heteroatoms in the chain
