✦ Synopsis

Swmary: Deprotonation of 2-diethyIumino-5-phenyZ-3!-azepine with strong bases affords a highZy coloured anion, which reacts with deuterim oxide or with an appropriate electrophile to give an azepine bearing the new substituent at C-3.

During the last decades several papers have appeared dealing with anions of seven-masbered ring systems, e.g. of cycloheptatrienes' and of 1,2-diazepines 2,3 . These negatively charged 8~
