Dichloromethane activation. Direct methylenation of ketones and aldehydes with CH2Cl2 promoted by Mg/TiCl4/THF

(Chemical Equation Presented) This Mg-TiCl4-promoted CH 2-transfer reaction of CH2Cl2 represents an extremely simple, practical, and efficient methylenation of a variety of ketones and aldehydes, especially in enolizable or sterically hindered ketones such as 2,2-dimethylcyclohexanone, camphor, and fenchone.

Palladium-Catalyzed Cyclization of Benzyl Halides and Related Electrophiles Containing Alkenes and Alkynes as a Novel Route to Carbocycles

Treatment of benzyl halides and related electrophiles containing alkene and alkyne groups with a catalytic amount of Pd complexes, such as Pd(PPh3)4, provides the corresponding cyclization products containing five- through seven-membered rings often with retention of the alkene regiochemistry.
