“…However, if a bulky triphenylsilyl group is introduced, monosilylhydrazines are formed and their disproportionation occur only at 90°C. Further, this class of monosilylated compounds, R 3 SiN 2 H 3 could be kinetically stabilized by the introduction of one or more bulky tert-butyl groups (for example; R = t Bu 2 F [17], t Bu 2 Me [18], t Bu 2 Ph [19] or t Bu(i-Pr) 2 [19]). Thus the bulkiness of the alkyl group plays an important role in imparting stability to these classes of compounds.…”
