  • METHOD FOR HYDROSILYLATION OF ALIPHATICALLY UNSATURATED ALKOXYSILANES AND HYDROGEN TERMINATED ORGANOSILOXANE OLIGOMERS TO PREPARE ALKOXYSILYL TERMINATED POLYMERS USEFUL FOR FUNCTIONALIZING POLYORGANOSILOXANES USING AN IRIDIUM CATALYST
    Publication number: 20200231756
    Abstract: A method for preparing a product includes combining starting materials including A) a siloxane oligomer having silicon bonded hydrogen atoms, B) an alkoxysilane having at least one aliphatically unsaturated group capable of undergoing hydrosilylation reaction and C) an iridium complex catalyst. The method can be used to produce a compound of formula (I). This compound can be used in a hydrosilylation reaction with a vinyl-functional polyorganosiloxane. The resulting product includes an ethyltrimethoxysilyl functional polyorganosiloxane useful in condensation reaction curable sealant compositions.

  • Process for heat-fractionation of organosilanes
    Patent number: 5545743
    Abstract: An improved process for the heat-fractionation of a mixture comprising an organosilane and a borane or borane forming compound. The improvement comprises the presence of a tertiary organoamine or tertiary phosphorous compound at a concentration sufficient to reduce modification of the organosilane during the heat-fractionation process.

  • Process for cycloalkyl substitution of hydrogen containing silanes
    Patent number: 5118829
    Abstract: The present invention is a process for substituting cycloalkyl substituents for a silicon bound hydrogen of a silane. The process employs a preformed organoborane compound as a catalyst to increase the apparent rate of the reaction and to increase the yield of desired cycloalkylsilanes.
