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 synthesis is proposed.
在80-100°下在邻二氯苯中用草酰卤处理2-仲-氨基链烯腈的氢卤化物得到3,5-二卤代-2(1H)-吡嗪酮,其中3-卤代取代基容易被亲核试剂取代。提出了吡嗪酮合成的反应机理。
