Embodiment 1
[0097] Example 1 (Synthesis of Polycyclopentasilane by Polymerization of Cyclopentasilane Using a Palladium Catalyst Loaded on a Polymer)
[0098] In an inert atmosphere, cyclopentasilane (0.8 g) was added to 0.44 mol % of a commercially available polymer-supported palladium catalyst (manufactured by Wako Pure Chemical Industries, Ltd., trade name PIPd (Pd content 3 mass %), 82.1 mg) glass sample tube, the reaction mixture was stirred for 1 hour in an uncorked sample tube. Next, the reaction was terminated with 5.14 g of cyclohexane to precipitate insoluble components, and the mixture was filtered through a polytetrafluoroethylene membrane filter with a pore diameter of 0.45 μm. Next, the solution was transferred to a pear-shaped flask, and volatile components were removed by reducing pressure (about 20 Torr or less, for example, 1 to 20 Torr). The product can be stored as an 8% by mass solution dissolved in distilled cyclooctane. As a result of measuring the product by gel ...
