METHOD FOR JOINT PRODUCTION OF E3,E8-DIMETHYL-TRANS-BICYCLO[4,4,0]DECANE AND E3,E9- DIMETHYL-TRANS-BICYCLO[4,4,0]DECANE Russian patent published in 2002 - IPC

FIELD: industrial organic synthesis. SUBSTANCE: in a method of joint production of E3,E8- and E3,E9- dimethyl-trans-bicyclo[4.4.0]decanes, which are applicable as solvents in varnish- and-paint industry as well as high-octane additives for motor fuels, reaction mixture composed by cyclohexane and organoaluminum compounds, in particular R₃Al and R_nAlCl_3-n, wherein R represents ethyl, propyl, or butyl and n = 1; 1.5; 2, is completed by carbon tetrachloride or chloroform. Reaction is conducted in presence of transition metal complex or salt, in particular , as catalyst in argon atmosphere, at normal pressure and temperature 10-60 C for 1 to 4 h. Molar ratio cyclohexane/organoaluminum compound/polychloromethane is 100: (4-13):(27-50). Amount of catalyst corresponds to 0.079-0.132 mol % based on initial cyclohexane. Yield of two products comes to 32-58% in one step. EFFECT: increased selectivity of reaction. 1 tbl, 12 ex
