Lewis acid like zinc bromide or aluminum chloride and results in the formation of pure thiobis (chloromethane) (2). This reagent has been successfully employed in the straightforward synthesis of a novel series of thiacrown ethers possessing methylene bridges between the heteroatoms. These molecules have chemical and physicalproperties that differ considerably in their solubilities from those of their
