TY - JOUR T1 - Well-defined calcium compound catalyzes trimerization of arylisocyanates into 1,3,5-triarylisocyanurates JF - ChemCatChem Y1 - 2022 A1 - Kumar, Rohit A1 - Sharma, Vishal A1 - Jain, Shailja A1 - Sharma, Himanshu A1 - Vanka, Kumar A1 - Sen, Sakya S.

We report the synthesis of a calcium complex (2) bearing a tetradentate monoanionic ligand with a diaminoethane core and phenolate and pyridine peripheral donors. Single crystal X-ray studies on 2 revealed that LiI was also co-crystallized, leading to a four-membered ring with four different elements. 2 was found to be an efficient catalyst for the cyclotrimerization of a variety of aromatic isocyanates under mild conditions.
