Quaternary hydrazonium salts

Quaternary hydrazonium salts (derived from aldehydes) give nitriles when treated with OEt or DBU (p. 488, 1337) as do dimethylhydrazones RCH— NNMe2 when treated with Et2NLi and HMPA. All these are methods of converting aldehyde derivatives to nitriles. For the conversion of aldehydes directly to nitriles, without isolation of intermediates, see 16-21. [Pg.1348]
