METHOD OF COMBINED SYNTHESIS OF 1-(ENDO- TRICYCLO-5.2.1.0^5,9 -DEC-7-ENE -2-YL)-1- (ISOBUTYL)-1-CHLORALANE AND 1-(ENDO- TRICYCLO- 5.2.1.0^5,9-DEC -6-ENE- 2-YL) -1- (ISOBUTYL) -1-CHLORALAN- E

摘要

FIELD: organic chemistry. SUBSTANCE: synthesis of indicated compounds is carried out by reaction of dicyclobutadiene with diethylaluminium chloride at their molar ratio 10:(10-12), preferably 10:11, at 40 C in the presence of bimetallic catalyst Cp₂ZrCl₂ and zirconium tetrachloride taken at the molar ratio 1:(0.5-1.5), better at 1:1, at concentration 2-5 (better at 3) mole with regard to Cp₂ZrCl₂, in argon atmosphere, in the medium of methylene chloride. Time reaction is 6-10 h, the yield of the end products is 82-95% EFFECT: improved method of synthesis, increased yield of products. 1 tbl
