WebOct 13, 2024 · Introduction. N, N’-Monosubstituted thiourea compounds are frequently applied to catalyze a broad range of reactions, including Diels-Alder reactions, 1-3 Michael additions, 4-8 Henry reaction, 9, 10 acetalization, 11-13 Mannich-type reactions, 14-19 as well as ring-opening polymerizations (ROP) 20-22 in a mild and often asymmetric fashion. … WebOrganic Chemistry Map: Organic Chemistry (Wade), Complete and Semesters I and II Map: Organic Chemistry (Wade) ... This problem can be solved by using thiourea, (NH 2) 2 C=S, as the nucleophile. The reaction first produces an alkyl isothiourea salt and an intermediate. This salt is then hydrolyzed by a reaction with aqueous base.
