Two- and three-coordinate m-terphenyl complexes of manganese and iron are efficient catalysts for the selective cyclotrimerisation of primary aliphatic isocyanates affording isocyanurates in short reaction times and under mild conditions.

The reaction of cyanogen bromide (1) with primary amines (2a-p), including arylmethylamines (21-p), gave the corresponding cyanamides (3a- p). Trimerization of 3a-p gave 1,3,5-trisubstituted 2,4,6-triiminohexahydro- 1,3,5-triazines (isomelamines) (4a-p), which were treated with hydrochloric acid to give the corresponding 1,3,5-trisubstituted 2,4,6-trioxohexahydro- 1,3,5-triazines (isocyanurates) (5a-c, f) and 1,3,5-trisubstituted 2-imino- 4,6-dioxohexahydro-1,3,5- triazines (5b'-e'). Biological evaluation of 4a- p, 5a-c, f, and 5b'-e' was carried out, and some of these compounds showed bronchodilator and positive inotropic activities.
