Two new air- and water-stable Pt(II) metallosupramolecular complexes based on ambidentate ligands have been designed, synthesized and fully characterized. The structure of complexes has been determined by various analytical techniques including NMR spectroscopy and TOF-MS. Additionally, the single crystal structure of 2 was determined by X-ray diffraction. The catalytic activity of these complexes in hydrosilylation has been investigated, establishing that both have similar high activity and selectivity within a broad scope of structurally distinct olefins and hydrosilanes.

Hydrosilylation of styrene, 2-phenyl-1-propene and trans-1-phenyl-1-propene by trialkylsilicon hydrides of the type CH3R2SiH (R = C2H5, i-C3H7, i-C4H9) catalysed by 3> in the presence of benzene, 1,3,5-triethylbenzene, 1,2,3,4-tetraethylbenzene, pentaethylbenzene, hexaethylbenzene, 1,2,3,4-tetrahydronaphthalene, cyclohexane, tetrahydrofuran (THF), tributylphosphate (TBP), dimethylacetamide (DMA), trimethylphosphate (TMP), tributylphosphate (TBP) and hexamethylphosphorictriamide (HMPA) has been studied both in anaerobic conditions and in the presence of air oxygen.Aromatic solvents were found to affect the composition of reaction products similarly as benzene.The use of THF, TBF, TMP, DMA and HMPA as solvents for hydrosilylation of styrene by the above silanes suppresses formation of the α-adduct when the reaction is carried out under unaerobic conditions.The yields of hydrosilylation of 2-phenyl-1-propene and trans-1-phenyl-1-propene by CH3(C2H5)2SiH are decreased by the addition of THF, TBP, TMP and DMA while they are increased by using HMPA as the solvent.
