Abstract
AbstractWe report a series of Zn(II) and Cd(II) metal complexes [L12(ZnCl2)] (1), [L12(ZnBr2)] (2), [L12(CdCl2)] (3), [L12(CdI2)] (4), [L22(ZnCl2)] (5), [L22(ZnBr2)] (6), [L22(ZnI2)] (7), [L22(CdCl2)] (8), [L32(CdCl2)] (9) and [L42(ZnBr2)] (10), synthesized using various unsymmetrical aryl thiourea ligands: 1‐(2,6‐diisopropylphenyl)‐3‐phenylthiourea (L1), 1‐mesityl‐3‐phenylthiourea (L2), 1‐(2‐fluorophenyl)‐3‐phenylthiourea (L3) and symmetrical 1,3‐bis(2‐fluorophenyl)thiourea (L4). The ligands and metal complexes were characterized by 1H, 13C{1H} NMR, FT‐IR analysis. Solid‐state structures of the zinc and cadmium metal complexes (1–8) were established using the single‐crystal diffraction analysis technique. Furthermore, the catalytic activities of the Zn(II) complexes towards hydroboration of aldehydes and ketones (‐C=O) as substrates were studied. Excellent yields of the corresponding boronate esters were achieved.
