^aRelative to dimethylphenylsilane (0.23 mmol).

^bApparent rate constant (k_app) and accessibility rate (r) determined according to eqn (5).

^cTime at 3% conversion was taken as the induction time (t_ind) and calculated using eqn (5).

^dReaction time (t_R) at 99% conversion, calculated using eqn (5).

^eRate constant normalized to the overall surface area of the embedded Au NPs (S_AuNP, Table 2) and the concentration of n-BuOH (c_n-BuOH = 10.93 mol L⁻¹); given errors were calculated based on error propagation (eqn (S12)).
