Abstract

A reaction of 7-alkyl-, 7-allyl-, 7-phenyl-1,3,5-cycloheptatrienes with 1,2-dienes in the presence of the two-component catalytic system Ti(acac)2Cl2—Et2AlCl, which led to the formation of practically important substituted endo-bicyclo[4.2.1]nona-2,4-dienes in up to 90% yields, was accomplished for the first time.
