Abstract
Highly stabilized carbanion and enolate salts, heterocycle-substituted sodiomalononitrile and sodiocyanoacetates, were synthesized via Pd-catalyzed ring-alkylation of bromoheterocyclic compounds and shown to be useful intermediates for the synthesis of various alkyl-substituted heterocyclic compounds.
