ETHYL 1,4-DIHYDROPYRIDINECARBODITHIOATES AND THE ELECTRONIC EFFECTS OF SULFUR-CONTAINING ESTER SUBSTITUENTS
Methods have been developed for the synthesis of the ethyl esters of 2,6-dimethyl-1,4-dihydropyridine-3,5-bis(carbodithioic) and 4-aryl-2-methyl-5-oxo-4,5-dihydro-1H-indenopyridine-3-carbodithioic acids.From the physicochemical properties (acid dis
