Transannulare Reaktionen von Cycloalkenen,Cycloalkadienen und Cycloalkatrienen. VIII. Zur elektrophilen Addition von Pseudohalogenen an Cycloocta-1(Z),5(Z)-dien

Transannular Reactions of Cycloalkenes, Cycloalkadienes and Cycloalkatrienes. VIII. The Electrophilic Addition of Pseudohalogenes to Cycloocta-1(Z), 5(Z)-diene The reaction of cycloocta-1(Z), 5(Z)-diene 5 with chlorothiocyanate is described. The main process is the normal anti-addition to produce trans-5-chloro-6-thiocyanato-(Z)-cyclooctene 6 . In addition 2,6-dichloro-9-thiabicyclo 3.3.1] nonane 7 and 2,6-dithiocyanato-9-thiabicyclo3.3.1] nonane 8 are obtained as products of a transannular reaction.
