Participants

Conditions

Temperature: 50 °C

Procedure

80 g (0.48 mol) of fluorine and 160 ml of toluene/12.8 ml (0.12 mol) of dimethoxyethane (DME) were placed in a reaction vessel and admixed with 182 ml (0.48 mol) of a 20% strength solution of butyllithium in toluene. The suspension was stirred for another 2 hours at 50° C. The suspension was diluted with 800 ml of heptane, cooled to −10° C. and 182 g (0.72 mol) of diphenyldichlorosilane were added all at once to the suspension.

Workup

temperaturecooled to −10° C.
