The Vilsmeier reagents generated from tertiary and secondary aliphatic and aromatic amides and trifluoromethanesulfonic anhydride (Tf2O) reacted with different nucleophiles (ROH, RSH, RNH2) affording the relative iminium and amidinium salts. The former, stable at room temperature, were easily transformed into the corresponding esters or O-alkyl thioesters by treatment with OH− or SH−.
由叔和仲脂肪族和芳香族酰胺以及三氟甲磺酸酐(Tf 2 O)生成的Vilsmeier试剂与不同的亲核试剂(ROH,RSH,RNH 2)反应,得到相对的亚胺鎓盐和am鎓盐。前者,在室温下稳定,通过用OH处理很容易转变成相应的酯或O-烷基硫酯-或SH - 。
