Abstrakt: 1.During isomerization of cis, trans, trans-l,5,9-cyclododecatriene under the action of polyphosphoric acid mainly 1a,3,4,5,6,7,8,8a- and 2a,3,4,5,6,7,8-octahydroacenaphthenes are obtained, and under the action of i-Bu3Al formation of tricyclo[7.3.0.O2,6]dodecenes is observed. A new catalytic system Cp2TiCl2-i-Bu3Al is proposed for isomerization of the latter type.2.Two new methods for obtaining 1,3-dimethyladamantane from cis,trans,trans-l,5,9-cyclododecatriene are proposed.
