The Cr=C bonds of aryl- and alkenyl(ethoxy)carbene chromium complexes 1a-d are hydrolysed under mild reaction conditions with high chemoselectivity in presence of hexamethylenetetramine (urotropine), 2, to give aldehydes 4a-d and (urotropine)Cr(CO)5, 3.The alkynyl(ethoxy)carbene chromium complex 1e reacts with urotropine in a completely different fashion and forms a binuclear (β-amino)vinylcarbene complex, 5, by fragmentation of the urotropine skeleton.
