Abstract
Upon treatment with aqueous alkali. the Diels-Alder adducts 2 and 4 of dich loromethylenepropane-dinitrile (1) with cyclopentadiene and anthracene resp . are converted into 3-chloro-bicyclo[2.2.1]hepta-2,5-diene-2-carbonitrile (3) and 12-chloro-9,10-dihydro-ethenoanthracene-11-carbonitrile (5). resp. The reaction may be brought about by other nucleophiles as well and involve s the fragmentation of an intermediate beta -chloroimidate anion. 3 is a ed uct for substituted norbornenes such as cyanoketone 18.
