cyclopropanes - Grignard reagent - titanium

Significance

In 1991, Kulinkovich and co-workers reported the titanium-catalyzed reaction of simple esters with ethylmagnesium bromide, leading to substituted cyclopropanols in excellent yields.


 

Comment

Interestingly, in the presence of the titanium catalyst, ethylmagnesium bromide is transformed into an ethylene dianion, which is reactive towards alkylcarboxylic esters.
