Synthesis of N-arylpiperazines from aryl halides and piperazine under a palladium Tri-tert-butylphosphine (cas 13716-12-6) catalyst

Add time:09/09/2019    Source:sciencedirect.com

A PdP(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.
