hydroxylamine tosylate reacts with aldehydes at room temperature to give the corresponding O-carbamoylated oximes. The reaction of carbamoylated hydroxylamine with aromatic aldehydes in THF or in toluene at reflux affords the corresponding nitriles and anilinium tosylate in high yield. Attempts to cyclize compounds 2 in the presence of AcCl lead again to the formation of nitriles.
O-芳基氨基甲酰基化的羟胺甲苯磺酸盐在室温下与醛反应,生成相应的O-氨基甲酰基化的肟。氨基甲酸酯化的羟胺与芳族醛在THF或甲苯中的反应在回流下进行,从而以高收率得到相应的腈和甲苯磺酸苯磺酸铵。尝试在AcCl存在下环化化合物2再次导致腈的形成。
