Efficient Copper(I)-Catalyzed C,S Cross Coupling of Thiols with Aryl Halides in Water

EUROPEAN JOURNAL OF ORGANIC CHEMISTRY, Issue 4 2008
Laxmidhar Rout
Abstract CuI efficiently catalyzes the C,S cross coupling of thiols with aryl halides in the presence of tetrabutylammonium bromide in water. The reactions with aryl thiols that have electron-withdrawing and -donating substituents are comparable and afford C,S cross-coupling products in high yield. (© Wiley-VCH Verlag GmbH & Co.

Copper-Catalyzed Preparation of ,-Alkylidenebutenolides and Isocoumarins under Mild Palladium-Free Conditions

ADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 5 2009
Samuel Inack-Ngi
Abstract A general and efficient copper(I)-catalyzed cross-coupling and heterocyclization reaction of terminal alkynes and ,-iodo-,,,-unsaturated acid derivatives has been developed under very mild conditions. This method provides easy access from good to excellent yields of a variety of 5-ylidenebutenolides and 3-substituted isocoumarins with excellent regio- and stereoselectivity. This procedure does not require the use of any expensive supplementary additives, and is palladium-free. [source]
