Abstract

A Pd P (t-Bu) 3 catalyst system has revealed very high activity and selectivity for the amination of N-(hetero) aryl halides with unprotected piperazine. A wide variety of N-(hetero) arylpiperazines could be prepared using this catalyst. Turnover numbers up to 6400mol/mol have been obtained.
