N-Phenylpyrrole: a kinetic, though not thermodynamic preference for dilithiation

Under appropriate conditions the clean prepn. of either the a-mono-lithiated or the o,a-dilithiated deriv. of N-phenylpyrrole is possible. In the latter case, the first deprotonation occurs at the a-position. Dimetalation is kinetically but not thermodynamically favored. [on SciFinder (R)]
