dimethoxy(diphenyl)silane

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Under a nitrogen gas atmosphere, 4.90 g (8.94 mmol) of 2,7-dibromo-9,9-dioctylfluorene, 20 ml of diethyl ether and 10 ml of toluene were added to a 100 ml three-necked flask equipped with a reflux condenser and a dropping funnel. Under cooling by an ice bath, 6.1 ml (9.76 mmol) of a hexane solution of n-butyllithium (1.6 M) was added dropwise. As the hexane solution of butyllithium was added dropwise, the solution turned red. The solution was agitated “as is” for approximately 1 hour; then, 1.03 g (4.21 mmol) of dimethoxydiphenylsilane was added, and this mixture was reacted under agitation all night. equipped with a reflux condenser and a dropping funnel Under cooling by an ice bath for approximately 1 hour this mixture was reacted under agitation all night
