Conditions

Temperature
40 °C

Procedure

To 2.230 g (7.41 mmol) of (trimethylsilylcyclopentadienyl)-trimethyltin is added 0.59 g (0.48 ml, 3.7 mmol) of dichloro-(phenyl)borane dropwise at room temperature. An intense yellow color immediately appears. The mixture is heated at 40° C. for 2 h whereupon the yellow color intensifies. This is followed by fractional distillation wherein the chlorotrimethylstannane formed can first be separated off. In the distillation, a heavy decomposition occurs from about 120° C. bath temperature to give a dark-red oil.
