Carbon tetrachloride is no longer used as a common solvent due to its toxicity and harmful environmental impact. The synthesis of gem-dichloroalkenes from aldehydes by using triphenylphosphine typically requires carbon tetrachloride as a solvent. We report that stoichiometric bromotrichloromethane in acetonitrile can be used in place of solvent quantities of carbon tetrachloride in this transformation. Similarly, bromotrichloromethane in dichloromethane can be used for the room-temperature Appel reaction of benzyl alcohols to form benzyl chlorides, which is commonly carried out in refluxing carbon tetrachloride.

Catalytic olefination of carbonyl compounds. Effect of the structure of the carbonyl compound on the reaction

The mechanism of the novel reaction of catalytic olefination of carbonyl compounds was studied. The reaction involves the transformation of hydrazones of aromatic aldehydes and ketones into the corresponding dichloroalkenes and symmetrical azines by the treatment with carbon tetrachloride in the presence of CuCl as a catalyst. The stability of intermediate diazoalkanes is the main factor determining the direction of the reaction. In the case of sufficiently stable diazoalkanes, other products can be formed under the reaction conditions along with the products of catalytic olefination.
