Barriers to internalrotation about the C(2)-C(3) bonds have been determined for ten closely related halogenated methylbutanes by detailed line-shape analysis of their nuclear magnetic resonance spectra. The experimental barriers range from 9 to 16 kcal/mol. In addition, for some of the compounds investigated, free energy differences were obtained for rotational isomers under conditions of slow conformational

The following new compounds were isolated from the vapor phase chlorination of butyne-1, butyne-2, and pentyne-1: 1,1,2,2-tetrachlorobutane, 2,2,3,3-tetra chlorobutane, 1,1,2,2-tetrachloropentane, trans-1,2-dichloro-1-butene, trans-2,3-dichloro-2-butene, and trans-1,2-dichloro-1-pentene. Dehydrochlorination of 1,1,2,2-tetrachlorobutane and 1,1,2,2-tetrachloropentane gave 1,1,2-trichloro-1-butene and
