Typical profile of the decay of amine during the reaction of N-methylbenzylamine (21.2 mM) with 4-chloroanisole (2a; 119 mM) catalyzed by Pd(PtBu3)2 (2.1 mM, 10%) and PtBu3 (0.21 mM, 1%) at 100 2°C and (A) NaOCEt3 (0.10–0.30 M) as base, (B) NaOtBu (0.10–0.30 M) as base, (C) 2,4,6-tri-tert-butylphenoxide (0.50–0.15 M) as base, and (D) 0.20 M NaOCEt3 as base with added [(C8H17)4N]-Br (5.0–15 mM).
