Procedures for the preparation of silanols

Two procedures are described for the preparation of silanols and silanediols from the corresponding chlorosilanes.The first procedure, a two-phase hydrolysis-extraction process, is- particularly convenient and suited to the preparation of a wide range of mono-silanols.Hydrolysis of dichlorosilanes by this procedure gives varied results depending on the structure of the dichlorosilane and specific reaction conditions.The second procedure, a modification of a published procedure, is especially beneficial for the preparation of silanols and silanediols prone to undergo self-condensation.
