The preparation and characterization of six 4-substituted tetrahydro-l,4-oxazine-3,5-diones and five 4-substituted tetrahydro-l,4-thiazine-3,5-diones is described. Upon flash vacuum pyrolysis at 700°C these give N-substituted acetamides and nitriles, and a mechanism for formation of these products is proposed. 相似文献
