POLYNITROALKYL DERIVATIVES OF SF5N=CCL2 - NITRATIONS OF SF5 IMINES

Polynitroalkyl SF5, imines have been synthesized from SF5N=CCl2 via nu cleophilic substitution and nitration reactions. Only in one instance was the SF5 imino moiety (SF5N=C-) affected by a nitration reagent; th e product was the fluorosulfonyl compound; very similar SF5 materials were not affected by the nitration reagent. The SF5N=C- moiety, when c ompared to the carbonyl group (O=C-), exhibited a strong tendency to l ower the melting points of nitro compounds. The crystal structures of three SF5, imines and one fluorosulfonyl imine have been determined.
