METHOD FOR PREPARING 1-ETHYL-3-METHYL-3-PHENYL-(ETHYL-, CYCLOPROPYL-)-4-ALKYLIDENECYCLOHEPTA-2-OXALANES Russian patent published in 2003 - IPC

Abstract RU 2213745 C1

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to method for preparing a novel organoaluminum compound. Invention describes method for preparing 1-ethyl-3-methyl-3-phenyl-(ethyl-, cyclopropyl-)-4-alkylidenecyclohepta-2- oxalane by interaction of terminal allene with triethylaluminium in the presence of CpZrCl2 as catalyst, in argon medium, in CH2Cl2 with CuCl and CH3RCO wherein R is Ph, C2H5 and cyclo-C3H5. Invention provides preparing the novel compound with high regioselectivity. New compound can be used in fine organic synthesis and as co- catalysts in oligo- and polymerization of olefins and coupled dienes. EFFECT: improved preparing method. 1 tbl, 10 ex
