4,4′-Bis(dichloroiodo)biphenyl and 3-(dichloroiodo)benzoic acid are convenient recyclable hypervalent iodine reagents for vicinal chloromethoxylation or iodomethoxylation of unsaturated compounds. The reactivity of these reagents in the reaction of vicinal halomethoxylation is generally similar to dichloroiodobenzene and the advantage of their use is that the reduced forms of these reagents can be easily separated from the reaction mixture and reused for the regeneration of the reagents.

Trichloroisocyanuric acid reacts with alkynes in the presence of water in acetone or acetonitrile to form α,α-dichloro ketones and in methanol to form α,α-dichlorodimethyl ketals.

Electrochemical oxidation of terminal acetylenes using a divided cell in the presence of NaI as a supporting electrolyte in MeOH brought about the efficient formation of the corresponding 1 -iodoacetylenes. On the other hand, use of LiCl instead of NaI un
Ozonolysis of substituted 1,2-dichloroethylenes in methanol: products and reaction course

Ozonolysis of trans-2,3-dichloro-2-butene (5a), of trans-3,4-dichloro-3-hexene (5b), and of 1,2-dichlorocyclohexene in methanol and in solutions of sodium methoxide in methanol have been examined.They afforded in high yields the corresponding ester fragments methyl acetate (6a), methyl propionate (6b), and dimethyl adipate (8) respectively.By trapping with phenylacetylene and formation of 1,1-dichloro-2,2-dimethoxy-2-phenylethane, the presence of methyl hypochlorite in the ozonolysis products was established.A reaction course has been proposed which is in accord with these results.
