This chemist used o-nitrocinnamic acid as the starting material for a process involving that molecule's dibromide as a derivative,in order to replace an unfeasible process that applied phosphorus pentachloride to the expensive isatin. This chemist Âfirstsynthesized a compound by adding zinc chloride to precipitate a Friedel-Craftfts reaction between resorcinol and phthalic anhydride. This chemist's reagent, an alkaline solution of potassium permanganate, is qualitatively used to test for the presence ofunsaturation. He accounted for the unusual reactivity of cyclopropane and cyclobutane ring-opening reactions, and explainedthe difficulty of making rings with seven carbons or more, by proposing the earliest instance of ring strain theory. Because itsdiscovery took place on the feast day of St. Barbara, this synthesizer of flfluorescein bestowed the name "barbituric acid" on theparent compound of barbiturates. He is the fiÂrst namesake of a reaction in which disodium phosphate and mCPBA oxidizeketones to esters. For 10 points, name this German organic chemist who synthesized indigo dye, and co-names an oxidationwith Victor Villiger
