Cyclopropyl Grignard reagents react with carbonyl compounds in the presence of diethyl phosphite to give homoallylicbromides. The reaction is effectively carried out under mild conditions in a one-pot fashion with moderate to good yields.
Cyanuric chloride–dimethylformamide mediated cleavage of cyclopropylcarbinols-synthesis of phenolic antioxidant and construction of a new vinylcyclopropane skeleton
A highly stereoselectivesynthesis of 1,3-butadienes and its higher enyl analogs has been developed through thermal dehydrative ring opening of cyclopropyl carbinols in dimethylsulphoxide.
