Reaction Steps
Hexabutyldistannoxane (2 equiv.) was slowly added dropwise with stirring to dimethyldichlorosilane (19), followed by heating to 180° C. for 4 hours and vacuum distillation to give bis(tri-n-butylstannyloxy)dimethylsilane 24. Equimolar amounts of 23 and 24 in THF were stirred at room temperature for 4 hours before cyclosiloxane 25 was isolated by distillation.
