Synthesis of triphenylpyridines <i>via</i> an oxidative cyclization reaction using Sr-doped LaCoO₃ perovskite as a recyclable heterogeneous catalyst

Abstract

An La_0.6Sr_0.4CoO₃ strontium-doped lanthanum cobaltite perovskite was prepared <italic>via</italic> a gelation and calcination approach and used as a heterogeneous catalyst for the synthesis of triphenylpyridines <italic>via</italic> the cyclization reaction between ketoximes and phenylacetic acids.
