(a) Initial rate for conversion of 7 into 8 over the first 10% as a function of catalyst loadings while holding initial azide 7 concentration constant. Every measurement is done in triplicate, and error bars represent standard deviations; (b) Initial rate for conversion of 7 into 8 over the first 10% as a function of initial azide 7 concentration while holding catalyst concentration constant. Every measurement is done in triplicate, and error bars represent standard deviations; (c) Plotting the first 10% conversion of 9H2 (blue) and 9D2 (red) into 10H and 10D over time, respectively. Intermolecular KIE is derived by taking the ratio of the slopes of the linear fits [KIE = 1.35 ± 0.03 (60 °C)]. Every measurement is done in triplicate, and error bars represent standard deviations.
