alcohols correlate best with a slightly larger negative slope (ρ=−0.48). The reaction of methanol with TBSCl catalyzed by 4‐(N,N‐dimethylamino)pyridine (DMAP) has been studied at several different theoretical levels in chloroform solution. Silyl‐group transfer between silylated DMAP and methanol occur over an exceedingly flat surface with barely defined minima and transition states. Reaction pathway calculations
