Reaction of FeCl3 with 7-chloro-1-silyloxybicycloheptanes : A way to 2-(1-chloroalkylidene)cyclohexanones.
Blanco, L.,Mansouri, A.
, p. 3239 - 3242 (2007/10/02)
The regioselectivity of the FeCl3-promoted cleavage of the title compounds was studied : 2-(1,1-dichloroalkyl)cyclohexanones were obtained which were converted to 2-(1-chloroalkylidene)cyclohexanones by dehydrochlorination.
