Abstract
The invention is a process for alkylating nitrogen acids using an electrogenerated base as a catalyst comprising (a) electro-reducing a probase at the cathode by electrolysis in an aprotic liquid electrolysis medium comprising a probase, an anhydrous aprotic solvent, and supporting electrolyte to produce an electrogenerated base, (b) deprotonating a nitrogen acid with the electrogenerated base to produce a nitrogen acid anion, and (c) reacting the nitrogen acid anion with an alkylating agent to produce an alkylated nitrogen acid; with the aforesaid probase being more easily electro-reducible than the nitrogen acid and producing an electrogenerated base strong enough to deprotonate the nitrogen acid which is sufficiently acidic to permit such deprotonation, and the electrogenerated base not reacting readily, unless rapidly reversibly, with the alkylating agent.
