Table 2. Comparison of Induction Period and Rate of Reaction (2a versus 5a)a.
Conditions: complex 2a or 5a (1 mol %), tert-butylphenylacetylene (0.25 mmol), HBpin (0.10 mmol), RT, CD3CN (500 μL). Spectroscopic consumption of tert-butylphenylacetylene measured by 1H NMR spectroscopy against 1,3,5-trimethoxybenzene.
