Ethyl propiolate undergoes one-pot three-step thioconjugate addition-oxidation-Diels鈥揂lder cycloaddition when treated with a variety of thiols in the presence of catalytic base, meta-chloroperbenzoic acid, lithium perchlorate, and cyclopentadiene. The reaction of S-aryl thiols is catalyzed by tri...
Draw both resonance structures of the anions formed by the reaction of the most acidic C-H bond of the two compounds below with base. Draw the conjugate bases of pyrrole and cyclopentadiene. Explain why the sp3 hybridized C-H bond of cyclopentadiene is more acidic than...
