Miyagawa, Ichiro published the artcileStudies on internal rotation by the measurement of dipole moments. IV. The dipole moments of some halogenated hydrocarbons, Product Details of C6H12Br2, the publication is Nippon Kagaku Kaishi (1921-47) (1954), 1162-5, database is CAplus.
cf. C.A. 48, 13297h. The dipole moments of 2,3-dichloro-2,3-dimethylbutane, 2,3-dibromo-2,3-dimethylbutane, 1,2-dibromo-2-methylpropane, and 1,1,2-tribromoethane were measured in heptane at -20° to 50°. The energy difference between a trans and a gauche form and the moment of the gauche form were calculated The moment of 1,1,2-tribromoethane is independent of temperature The moment of this compound corresponds to that of the gauche form rather than to that of the Cs form.
Nippon Kagaku Kaishi (1921-47) published new progress about 594-81-0. 594-81-0 belongs to bromides-buliding-blocks, auxiliary class Bromide,Aliphatic hydrocarbon chain, name is 2,3-Dibromo-2,3-dimethylbutane, and the molecular formula is C6H12Br2, Product Details of C6H12Br2.
