Abstract
Sulfonation of pyrrole and its 1-methyl derivatives with a sulfur trioxide–pyridine complex was found to give 3-sulfonated pyrroles, but not 2-sulfonates as described in textbooks. The replacement of 1-methyl-2-tri-n-butylstannylpyrrole with trimethylsilyl chlorosulfonate, followed by quenching with aq. NaHCO3 also generated sodium 1-methylpyrrole-3-sulfonate, not 2-sulfonate.
