Abstract
The reaction of alkynyl alkoxy metal (Cr, W) carbene complexes with 1, 3-dinitrogen systems (amidines, guanidines, ureas) is described. In al l cases, the main product obtained corresponds to the cycloadduct whos e cyclic structure may be related to a pyrimidinic ring arising from a formal [3 + 3] cycloaddition, between the metal carbene complexes and the dinitrogen systems.
