摘要

Abstract A one pot reaction involving sym N, N′-diarylthiourea and the respective arylamine in the presence of aq. KOH in nitrobenzene at≥ 105° C afforded sym N, N′, N ″- triarylguanidine in fair to good yield and the products have been characterized. Sym N, N′, N ″-tri (4-tolyl) guanidine possesses (7) anti-anti conformation, sym N, N′, N ″-tri (2-tolyl) guanidine (8) and sym N, N', N ″-tris (2, 4-xylyl) guanidine (11) each possess anti-anti ...
