Regioselectivity in the rhodium catalysed 1,4-hydrosilylation of isoprene. Aspects on reaction conditions and ligands
(2004) In Journal of Organometallic Chemistry 689(2). p.438-443- Abstract
- The regioselectivity in the Rh catalysed 1,4-hydrosilylation of isoprene was investigated. Variation of solvents and temperature did not significantly affect the isomer distribution between tail-product (I) and head-product (II). The choice of ligands had the greater influence, where Rh-I-based catalysts with the strong electron withdrawing ligand CO favoured production of isomer II, while Rh-I catalysts with strong electron donating ligands (for example triarylphosphines) gave isomer I as the main product. In contrast to the square planar carbonyl complex RhCl(CO)(PPh3)(2), the square planar thiocarbonyl complex RhCl(CS)(PPh3)(2), gave I as the major isomer. (C) 2003 Elsevier B.V. All rights reserved.
