METHOD OF OBTAINING Si-CONTAINING BIS-(ENDO-BICYCLO4.2.1NONA-2,4,7-TRIENES)

摘要

FIELD: chemistry.;SUBSTANCE: claimed is method of obtaining Si-containing bis-(endo-bicyclo[4.2.1]nona-2,4,7-trienes) by interaction of Si-containing α,ω-diacetylenes with 1,3,5-cycloheptatriene in presence of catalytic system TiCl4-Et2AlCl at temperature 20-80°C, in benzene for 14-48 h. Method makes it possible to obtain individual Si-containing bis-(endo-bicyclo[4.2.1]nona-2,4,7-trienes), which can be components of high energy fuels for air-reactive rocket systems and products in synthesis of a number of medications.;EFFECT: increased output.;1 tbl, 10 ex
