Alkylidenation of Ketones by gem-Dibromoalkane, SmI2, and Sm in the Presence of Catalytic Amount of CrCl3

Alkylidenation of ketones can be performed by the reaction with geminal dibromoalkane-SmI2-Sm in the presence of catalytic amount of CrCl3 at room temperature yielding the alkylidenated products in good to excellent yields.

Alkylidenation of carbonyl compounds with gem-dizincioalkanes mediated with titanium dichloride

Olefination of carbonyl compounds with gem-dizincio-alkanes, bis(iodozincio)methane, 1,1-bis(iodozincio)ethane, and bis(bromozincio)methyltrimethylsilane, afforded the corresponding olefins in good to excellent yields.

EFFICIENT OLEFINATION WITH α-ALKYL CYCLIC PHOSPHONAMIDES

A variety of acyclic and cyclic aldehydes and ketones can be converted into the corresponding alkylidene, benzylidene and methoxycarbonyl alkylidene derivatives by treatment with 1,3,2-diazaphospholidine-2-alkyl-1,3-dimethyl 2-oxides (α-alkyl cyclic phosphonamides) under mild conditions.This olefination method is particularly useful in the case of enolizable carbonyl compounds.
