- Ferrocene promoted addition of methyl 2,2-dichloro-carboxylates to 1-alkenes
-
The Kharasch addition of methyl 2,2-dichlorocarboxylates to 1-alkenes is promoted by ferrocene in DMF at 100°C, affording 1:1 adducts in satisfactory yields.

- Trichloroisocyanuric Acid Oxidation of 2-Chloro Aldehyde Acetals to 2-Chloro Acids Esters
-
2-Chloro acid methyl esters were prepared in good yields treating 2-chloro aldehyde dimethyl acetals with trichloroisocyanuric acid in DMF.Aldehyde dimethyl acetals with the 2-halogen on a tertiary carbon atom were poorly reactive and could be oxidized efficiently only after their transformation into 1,3-dioxolanes.

- Applications of Phase-Transfer Catalysis, 35. - A Novel Reaction of Trichloroacetate

Unexpectedly, the phase-transfer catalyzed reaction between sodium trichloroacetate and alkyl halides yields alkyl 2,2-dichloro-4-pentenoates (2 or 4a-c, respectively).Alkyl trichloroacetates (1, 3a-c), the primary products, are dechlorinated by CCl3
