Cyclopropylphosphine oxides (140) react with the sodium salts of amides, presumably via cyclopropane ring-opening and intramolecular olefination, to give dihydropyrrole derivatives in moderate to good yield. Vicarious nucleophilic substitution reactions of a variety of substituted nitrobenzene derivatives with the carbanion of chloromethyldiphenylphosphine oxide to give o-(141) and p-(142)-nitrobenzyldiphenylphosphine oxides have been investigated. ...
