Formamidine urea compounds exchange imine fragments with primary nitrogen nucleophiles, allowing the preparation of a variety of derivatives from a single precursor. The reactivities of these species are governed primarily by the electron-donating power of the substituents and are tunable over a range of >10(3) in first-order rates of hydrolysis.
甲am脲化合物可与伯氮亲核试剂交换亚胺片段,从而可从单一前体制备各种衍生物。这些物质的反应性主要由取代基的供电子能力决定,在一级水解速率的范围内,可调节范围在> 10(3)范围内。
