Reactivity of a carbonyl moiety in organotin(IV) compounds: novel Pd(II) and Cu(II) complexes supported by organotin(IV) ligands

摘要: Hydrolysis of [2-{(CH2O)2CH}C6H4]SnPh3 (1) results in the isolation [2-(OCH)C6H4]SnPh3 (2) a very good yield. Reduction 2 with NaBH4 gives an almost quantitative yield [2-(HOCH2)C6H4]SnPh3 (3), when is treated appropriate amines absence any solvent, [2-(4′-PyCH2NCH)C6H4]SnPh3 (4) and [2-{3′,5′-(MeOOC)2–C6H3NCH}C6H4]SnPh3 (5) are isolated high yields. Adding to THF solution 4 leads [2-(4′-PyCH2NH–CH2)C6H4]SnPh3·BH3 (6), first aryltin(IV) compound ligand containing secondary amine functional group coordinated metal centre. The reaction [PdCl2(NCMe)2] [Cu(hfac)2·(H2O)] (hfac = hexafluoroacetylacetonate) 2 : 1 molar ratio gave corresponding heterometallic complexes [{2-(4′-PyCH2NCH2)C6H4SnPh3}2PdCl2] (7) [{2-(4′-PyCH2NCH2)C6H4SnPh3}2Cu(hfac)2] (8), respectively. purity compounds was confirmed by elemental analysis high-resolution mass spectrometry. Multinuclear NMR spectroscopy used investigate behaviour these molecular structures for 1, 2, 4–8 were established single-crystal X-ray diffraction.
