METHOD FOR JOINT PREPARATION OF E3,E8-DIMETHYL-TRANS- BICYCLO[4,4,0]DECANE AND E3,E9-DIMETHYL-TRANS-BICYCLO[4,4,0]DECANE Russian patent published in 2004 - IPC

Abstract RU 2221764 C2

FIELD: organic synthesis. SUBSTANCE: title compounds, which can find use as solvents in varnish-and- paint industry, high-octane additives for motor oils, and raw materials in organic synthesis, are prepared by reaction of cyclohexane with carbon tetrachloride in presence of aluminum powder preliminarily activated with iodine at molar ratio C₆H₁₂/CCl₄/Al 5:1.5:1. Reaction is carried out for 1 h at 40 C and atmospheric pressure. Summary yield of desired compounds is 59%. EFFECT: enabled safe implementation of synthesis due to elimination of use of explosive organo-aluminum compounds.
