STUDIES IN SILICO-ORGANIC COMPOUNDS. V. THE PREPARATION AND PROPERTIES OF CERTAIN POLYETHERS FROM TETRACHLOROSILANE, HEXACHLORODISILANE, AND HEXACHLORODISILOXANE1
A reaction of activated silicon with alcohols in an autoclave at 240—270 °C was studied. It was found that primaryalcohols form tetraalkoxysilanes Si(OR)4 with high selectivity (up to 97%), while the secondary PriOH gave a mixture of compounds HSi(OPri)3, Si(OPri)4, HSi(OPri)2OSi(OPri)2H, HSi(OPri)2OSi(OPri)3, and Si(OPri)3OSi(OPri)3 with the predominance of trialkoxysilane (up to 67%).
