METHOD FOR CO-PREPARING 3-THIATETRACYCLO[5.5.1.0•0]- TRIDEC-9-ENE AND 3-THIATETRACYCLO[5.5.1.0•0]TRICENE-10-ENE Russian patent published in 2004 - IPC

Abstract RU 2220966 C2

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method for co- preparing 3-thiatetracyclo[5.5.1.0^2,6•0^8,12]tridec-9-ene of the formula (1) 5.5.1.0^2,6•0^8,12 and 3-thiatetracyclo[5.5.1.0^2,6•0^8,12]tridec-10-ene of the formula (2) . Method involves interaction of tricyclo[5.5.1.0^2,6•0^8,12] -3,8-decadiene with triethylaluminium in argon atmosphere, in heptane medium, in the presence of zirconacene dichloride () as a catalyst, at room temperature for 18 h followed by cooling reaction mass to 40C, addition of thionyl chloride 5.2.1.0^2,6 and stirring at this temperature for 6-8 h. The total yield of end products is 67-82%. Prepared compounds can be used as accelerating agents in rubber vulcanization process, addition agents for lubricating oils and fuels. EFFECT: improved preparing method. 1 tbl, 1 ex
