摘要

Abstract Mechanochemical methods of neat grinding and liquid-assisted grinding have been applied to the synthesis of mono-and bis (thiourea) s by using the click coupling of aromatic and aliphatic diamines with aromatic isothiocyanates. The ability to modify the reaction conditions allowed the optimization of each reaction, leading to the quantitative formation of chiral bis (thiourea) s with known uses as organocatalysts or anion sensors. Quantitative ...
