Abstract
A range of phosphine- and phosphite-substituted carbonylcobalt(0) complexes have been synthesised and screened as catalysts of the Pauson Khand annela tion. The readily prepared stable solid, heptacarbonyl(triphenylphosphine)d icobalt(0) 1. performed well (78% yield) in a benchmark annelation reaction . (C) 2001 Elsevier Science Ltd. All rights reserved.
