Earth-abundant main group metals are inherently labile, which has hitherto hindered their use in catalysis. In the present paper, we show that such lability can actually be exploited, by providing a dynamic coordination sphere that promotes the aluminum-catalyzed synthesis of isocyanurates. Isocyanurates find widespread use in building insulation and in the coatings industry and are prepared by the nucleophile-catalyzed trimerization of isocyanates, yet high catalyst loadings and substantially elevated temperatures are generally required. For the first time we report a highly active catalyst that trimerizes alkyl, allyl and aryl isocyanates, and di-isocyanates, with low catalyst loadings under mild conditions, based on aluminum bearing a hemi-labile pyridyl-bis(iminophenolate) ligand.

Dataset contains raw unprocessed data (the processed data were given in the supplementary information relating to the publication) as follows:

NMR spectroscopic data of metal complexes and catalysis products

Computational chemistry data (output files)

X-ray diffraction data for metal complexes and catalysis products

Infrared spectroscopic data for catalysis products

Mass spectrometry data for metal complexes and catalysis products.
