It has been characterized by IR, XPS spectra as well as elementary analysis. The results show that the number bonded Pt(PPh3)2 to C60 is 8.展开更多
Polysiloxane with fullerene moiety and its platinum complex have been prepared from (C\-2H\-5O)\-2CH\-3SiCH\-2CH\-2CH\-2NHCH\-2CH\-2NH\-2 via polymerization with (C\-2H\-6SiO)\-4 in the presence of (CH\-3)\-4NOH, foll...Polysiloxane with fullerene moiety and its platinum complex have been prepared from (C\-2H\-5O)\-2CH\-3SiCH\-2CH\-2CH\-2NHCH\-2CH\-2NH\-2 via polymerization with (C\-2H\-6SiO)\-4 in the presence of (CH\-3)\-4NOH, followed by the reaction with C 60 , then the complex reacting with potassium chloroplatinite in acetone under argon atmosphere. The Pt complex is an effective catalyst for hydrosilylation of olefin with triethoxysilane. It is found that the regioselectivity increases remarkably by the introduction C 60 moiety.展开更多
A silica-supported cross-linked poly(maleic acid -co- styrene)-platinum complex (PMS-Pt) has been prepared and found to be active in the hydrogenation of p-cresol under mild conditions (303-323K, 1.01 x 10(5)Pa). In t...A silica-supported cross-linked poly(maleic acid -co- styrene)-platinum complex (PMS-Pt) has been prepared and found to be active in the hydrogenation of p-cresol under mild conditions (303-323K, 1.01 x 10(5)Pa). In this hydrogenation system water serves as a solvent and p-cresol can be converted to 4-methylcyclohexanol quantitatively via 4-methylcyclohexanone as intermediate.展开更多
