Cover Picture: On the Nature of the Active Species in Palladium Catalyzed Mizoroki–Heck and Suzuki–Miyaura Couplings – Homogeneous or Heterogeneous Catalysis, A Critical Review: (Adv. Synth. Catal. 6/2006)

Abstract

The cover picture shows several forms of palladium which have been utilized as precatalysts for Heck and Suzuki coupling reactions. Over the years myriad different precat-alysts have been used and the nature of the true catalytic palladium species has been a subject of intense debate. What is the real catalyst in these reactions? For more details see the review by Nam T. S. Phan, Matthew Van Der Sluys and Christopher W. Jones on pages 609–679.
