请问：以下粗体字的意思? H2PtCl6.6H2O- Catalyzed Reactions of 1-Pentene and Styrene. As given in Table 1, the arachno-6,8-C2B7H13 and either H2- PtCl6.6H2Owere added to a 100 mL Schlenk tube, equipped with a magnetic stirbar, under a N2 purge. Either 1-pentene or styrene was added via syringe, and then the reaction vessel was degassed on the high-vacuum line. The chloroplatinic acid-catalyzed reactions were stirred in a 60 °C oil bath. In the chloroplatinic acid-catalyzed reaction with styrene, toluene (3 mL) was added to prevent gelling of the solution. The reaction products were isolated and purified by passing the product mixture through a 1/1 mixture of Celite 545/activated charcoal followed by flash column chromatography to yield analytically pure samples (Table 1).Sample TextSample Text sun-wen-bing@163.com [ Last edited by SWB888 on 2006-5-19 at 07:46 ] |
