摘要
The condensation reaction has been carryout very conveniently to obtain the corresponding substituted olefins in excellent yields and showing all the products in excellent E-geometry. The reaction conditions are very mild and applicable to various aldehydes as well as active methylene compounds. (c) 2005 Elsevier B.V. All rights reserved.
