Conditions

Temperature
80 °C

Procedure

18.77 g (0.159 mol) allylbenzene and 50 μl H2PtCl6/IPA solution were added to a 100 ml vessel. Solution was heated up to 80° C. and 41.85 g (0.159 mol) 1,1,1,4,4-pentachloro-1,4-disilabutane was added slowly during 30 min. Heat was switched off when exothermic reaction was observed. Temperature during the addition was kept below 130° C. After addition heat was again switched on and solution was stirred for an hour at 110° C. After that product was purified by distillation. B.p. 137° C./0.8 mbar. Yield 35.10 g (58%).
