Abstract: Four novel complexcs were obtained by reaoting H2PtCl6·6H2O or Na2PtCl6 with 18 Crown-6 and 1, 7, 10, 16-tetraoxa-4, 13-diazacyclooctadecane in molar ratio of 1:2 and 1:1 respectively. The complexes arc stable and slightsoluble or unsoluble in common organic solvents. In hydrosilylation of unsaturated compounds the complexes show a high catalytic activity at 80℃ and can be recovered and reused for several times. The activity of the complexes are, however, lower than that of H2PtCl6 or Na2PtCl6 alone when the hydrosilylation is carried out at 40℃ or room temperature.
