1364-548X58592022Jul21Chemical communications (Cambridge, England)Chem Commun (Camb)Solvent-free Zn (NSNO) complex-catalysed dihydroboration of nitriles.826682698266-826910.1039/d2cc03517kN-donors are the most commonly employed Lewis bases in ligand-assisted catalysis. A dimeric zinc complex (Zn-1) employing a tetradentate pyridine-thioether-anilido-aryloxide NSNO ligand (L) effects the quantitative conversion of nitriles to the corresponding double hydroborated products at 1 mol% catalyst loading. Variable Time Normalization Analysis kinetic studies showed a first-order dependence with respect to the nitrile, pinacolborane and zinc and clear evidence for catalyst deactivation. A plausible ligand-assisted reaction pathway involves B-H bond activation by the aryloxide (vs. anilido) donor.AtaieSaeedS0000-0001-8247-1321Department of Chemistry and Biomolecular Sciences and Centre for Catalysis Research and Innovation, University of Ottawa, Ottawa, Ontario K1N 6N5, Canada. rbaker@uottawa.ca.OvensJeffrey SJSFaculty of Science, University of Ottawa, Ottawa, Ontario K1N 6N5, Canada.Tom BakerRR0000-0002-1133-7149Department of Chemistry and Biomolecular Sciences and Centre for Catalysis Research and Innovation, University of Ottawa, Ottawa, Ontario K1N 6N5, Canada. rbaker@uottawa.ca.engJournal Article20220721
