(PCy3)2Cl2RuCHPh Catalyzed Kharasch additions. Application in a formal olefin carbonylation
摘要:
(PCy3)(2)Cl2Ru=CHPh-catalyzed Kharasch additions of trihaloalkanes across olefins provide polyhalogenated adducts, which upon hydrolysis furnish alpha,beta-unsaturated ketones, aldehydes, or gamma-hydroxybutenolides. This two-step process represents an overall acylation or carbonylation of an olefin. (C) 2004 Elsevier Ltd. All rights reserved.
