The first examples of intermolecular Diels-Alder reactions of aminocarbene complexes are described. Various members of both the alkylamino and acylamino families of complexes are investigated. The E-isomer of [tran-propenyl(methylamino)methylene]pentacarbonyltungsten (22) will react with Danishefsky's diene and 1-methoxy-1,3-butadiene, but the Z-isomer will not. The yields are good only for the more
