Pyrolysis of N,N-dichlorobenzenesulfonamide produced benzene (41percent) and chlorobenzene (40percent); the dibromo compound gave benzene (19percent) and bromobenzene (20percent).Toluene (46percent), chlorotoluene (27percent), and dichlorotoluene (10percent) were generated from the N,N-dichloro-p-tolyl derivative.From each aryl substrate, 1,1,2,2-tetrachloroethane was also produced from reactions involving CH2Cl2 solvent. 3-Chloro-N,N-dichloroadamantane-1-sulfonamide decomposed to 1,3-dichloroadamantane (52percent) and 1,3,5-trichloroadamantane (15percent).N,N-Dihalobenzamides produced phenyl isocyanate; N,N-dichloro and N-bromo derivatives gave isocyanate in 16-23percent and 21-28percent yields, respectively.N,N-Dichloroadamantane-1-carboxamide produced 1-adamantyl isocyanate (20-50percent) and 1-chloroadamantane (12-46percent).The mechanistic features of the various reactions are discussed.

Paragraph 0030; 0034, (2018/09/02)
PROBLEM TO BE SOLVED: To provide a production method suitable for industrial production of dichloroadamantanes. SOLUTION: A method for producing dichloroadamantanes represented by formula (2) is provided, in which adamantanes represented by formula (1) are mixed with thionyl chloride by 4 to 10 times moles to 1 mole of the adamantanes in the presence of sulfuric acid to react. In formula (1), R1 to R3 each independently represent H, a halogen atom, an alkyl group or an aryl group, and when R1 to R3 represent Cl, the number of Cl is at most 1, and when no Cl is included, at least one of R1 to R3 is H. In formula (2), one of R4 to R6 is a chlorine atom. SELECTED DRAWING: None COPYRIGHT: (C)2016,JPO&INPIT

The feasibility of catalytic chlorination of adamantane and its derivatives by carbon tetrachloride in the presence of manganese-, vanadium-, and molybdenum-containing catalysts activated by nitrile ligands or alcohols was established. The optimum molar ratios of catalyst components and reactants and the optimum reaction conditions for selective syntheses of mono-, di-, and trichlorosubstituted adamantane derivatives with high yields were found.
CATALYTIC BROMINATION OF ADAMANTANE IN 1,1,2-TRICHLORO-1,2,2-TRIFLUOROETHANE AND PERFLUOROBENZENE

The catalytic bromination of adamantane with bromine in 1,1,2-trifluoro-1,2,2-trifluoroethane (Freon 113) or perfluorobenzene in the presence of iron leads to 1,3-dibromoadamantane.In the presence of aluminum chloride in 1,1,2-trichloro-1,2,2-trifluoroethane a complex mixture of polychlorobromoadamantanes is formed on account of the chlorination of the adamantane by the solvent.
