Diazonium salts efficiently serve as electrophilic aminating reagents of esters. The reaction of arenediazonium tetrafluoroborates with ketene silyl ketals yielded α-azo or α-hydrazono esters in good to excellent yields under very mild conditions. Hydrogenation of those esters gave α-amino esters quantitatively.
重氮盐有效地用作酯的亲电胺化剂。四氟硼酸芳族重氮鎓与乙烯酮甲硅烷基缩酮的反应在非常温和的条件下以良好或优异的收率得到了α-偶氮或α-肼基酯。这些酯的氢化定量地得到α-氨基酯。
