Reaction of trans 2 phenyl
WebThere are two possible combinations of reactants because either of the two carbon atoms bonded to nitrogen could be derived from a carbonyl carbon atom. Either of the remaining carbon atoms in each case could be bonded to a nitrogen atom of an amine. The required carbonyl compound using methylamine as the reactant is 1-hydroxy-l-phenyl-2-propanone. WebThe reaction between the title compounds produces [4+2] Diets-Alder cycloadducts; the stereochemistry of the reaction is deduced from H-1 NMR data. 掌桥科研 一站式科研服务平台 学术工具
