WebCarboxylic acids were converted directly in good yields into ketones using excess alkyl cyanocuprates (R 2 CuLi•LiCN). A substrate with a stereocenter α to the carboxylic acid was converted with very little loss of enantiomeric purity. A variety of functional groups were tolerated including aryl bromides. This direct transformation involves ... WebI A comparative study of the energetics, structures, and mechanisms of the HCN H HNC and LiCN H LiNC isomerizations V.
