A catalyst- and additive-free synthesis of alkoxyhydrosiloxanes from silanols and alkoxyhydrosilanes. Issue 59 (18th June 2020) - Satoh, Yasushi
Abstract : A convenient method for the selective synthesis of alkoxyhydrosiloxanes that bear SiH and SiOR groups on the same silicon atom via a catalyst- and additive-free dealcoholization reaction between silanols and alkoxyhydrosilanes has been developed. Abstract : A convenient method for the selective synthesis of alkoxyhydrosiloxanes that bear SiH and SiOR 2 groups on the same silicon atom, R 1 3 Si–O–SiR 3 2− n (OR 2 ) n H ( n = 0, 1, or 2), via a simple catalyst- and additive-free dealcoholization reaction between silanols and alkoxyhydrosilanes has been developed. These alkoxyhydrosiloxanes can be easily converted into Si(OR 2 )3 -containing siloxanes by zinc catalyzed alkoxylation and alkoxy-containing silphenylene polymers by platinum catalyzed hydrosilylation.
