1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Formula: C13H9Cl3N2O

Synthetic and mechanistic aspects of anionic polymerization of methyl methacrylate using tetrabutyl ammonium thioimidate was written by Ge, Fang;Zhang, Qun;Wang, Xiaowu. And the article was included in Journal of Polymer Science (Hoboken, NJ, United States) in 2021.Formula: C13H9Cl3N2O This article mentions the following:

The tetrabutylammonium salts of ionic organo-initiator containing N,N’-diisopropylthiourea (TUA-1) or N,N’-diethylthiourea (TUA-2) serve as inexpensive initiators for the anionic polymerization of Me methacrylate (MMA) at room temperature The mol. weights of obtained polymers are in the range of 1500-22,700 g mol-1 and the mol. weight distributions are fairly broad (D = 1.9-2.5) in optimized cases. The molar ratio of monomer to initiator can be achieved up to 800. Side-reactions, for example, backbiting, transfer reactions result in the polymerization being a non-living manner, thus leading to broad mol. weight distributions of the resulting polymers. The effects of counterion nature were also studied from the polymerization of MMA using TUA-1 anion with sodium or potassium salts as counterions under identical conditions. Detailed investigation indicates that the polymerization proceeds via a sulfur anion initiated repeated 1,4-Michael addition In general, thioimidate initiators induced MMA polymerization feature certain induction periods, which is ascribed to slow addition thioimidate to C=C double bond of MMA as a result of low initiator efficiency. In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Formula: C13H9Cl3N2O).
