    • To confirm C-N activation in solution we reoptimized 3 S with a continuum model (Poisson-Boltzmann) implemented in the Jaguar program (Jaguar, 5.0 edit., Schrödinger, Inc., Portland, OR, 2003). This optimization failed with the PCM method implemented in Gaussian 98. In solution the C-N bond (1.521 Å) is even more stretched than in the gas phase (1.487 Å).
