addition products, depending on the nitrocompound and catalyst. The former product was favoured by the use of CuII in the catalytic system. Conversely, [60]fullerene underwent catalytic condensation, even in the absence of copper(II) salts, only with activatednitrocompounds and addition only with nitroalkanes in excess base. Note, the formal conjugated fullerene addition product was obtained in

Unusual sigmoidal kineticprofiles in the Machetti-De Sarlo base-catalyzed 1,3-dipolar cycloaddition of acrylamide to N-methylnitroacetamide are rationalized by detailed in situ kinetic analysis. A dual role is uncovered in which a substrate acts as a precursor to catalyze its own reaction. Such kinetic studies provide a general protocol for distinguishing among different mechanistic origins of induction
通过详细的原位动力学分析,Machetti-De Sarlo 碱催化的丙烯酰胺向 N-甲基硝基乙酰胺的 1,3-偶极环加成反应中异常的 S 形动力学曲线得以合理化。揭示了一种双重作用,其中底物充当催化其自身反应的前体。这种动力学研究提供了一个通用协议,用于区分复杂有机反应中诱导期的不同机械起源。
