The preparation of α-oxo acid derivatives suitable for specific-radioactivity determination
1. Conditions favouring the condensation of o-phenylenediamine with α-oxo acids to form substituted quinoxalines have been investigated. The best yields (85–100%) are obtained by incubation of the reagents in 2m-hydrochloric acid. Substitution of acetic acid for hydrochloric acid, or of halogen-subs...
