Abstract

The system Cp2TiCl2−LiAlH4, in the absence of ethereal solvents, catalyzes the intramolecular cyclization of Z,E,E-1,5,9-cyclododecatriene, yielding a mixture of C12 hydrocarbons consisting mainly of cis, anti, cis-and cis, syn, trans-tricyclo [7.3.0.02,6] dodec-7-ene and 5,6,7,8,9,10-hexahydrobenzocyclooctene.

Abstract

Система Cp2TiCl2−LiAlH4, в отсутствии эфирных растворителеь, катализирует внутримолекулярную циклизацию Z,E,E,-1,5,9-циклододекатриена, давая смесь углеводородов C12, состоящих преимущественно из цис, анти, цис-и цис, син, транс-трицикло [7.3.0.0.2,6] додекена-7, и 5,6,7,8,9,10-гексагидробензоциклооктена.
