title: A novel and efficient method for the olefination of carbonyl compounds with  Grignard reagents in the presence of diethyl phosphite.
abstract: The widely available carbonyl compounds react with Grignard reagents in the presence of diethyl phosphite to give the corresponding olefins in good to excellent yields: A range of conjugated dienes, terminal olefins, multisubstituted-alkenes and conjugated enynes could be readily obtained by the method in mild conditions.
