The title compounds were obtained from reaction of variously substituted 2(1H)pyrazinones with acetylenic derivatives.Experimental evidence points out to a two step mechanism: a Diels Alder cycloaddition followed by immediate decomposition of the adducts

The hydrohalides of 2-sec-aminoalkanenitriles on treatment with oxalyl halides in o-dichlorobenzene at 80-100° give 3,5-dihalo-2(1H)-pyrazinones, of which the 3-halo substituent is easily replaced by nucleophiles. A reaction mechanism for the pyrazinone s
