-
Paragraph 0033-0034, (2017/04/11)
PROBLEM TO BE SOLVED: To provide a method for easily producing high quality alkoxysilane without sublimating contaminant urea and urea hydroxide in the distillation of an alkoxysilane layer after separating an alcohol solution layer with urea and urea hydroxide dissolved therein when chlorosilane is reacted with alcohol in a presence of urea. SOLUTION: The method for producing organoxysilane represented by formula (3) comprises: reacting chlorosilane represented by formula (1) with alcohol represented by formula (2) in a presence of urea; removing hydrogen chloride generated by the above reaction, urea hydroxide produced by reaction of urea, and urea in a reaction system as an alcohol solution dissolved in alcohol in the reaction system from the system; and thereafter distilling an obtained organoxysilane layer with metal alkoxide added to the layer, where R1 and R2 are monovalent hydrocarbon groups, a is an integer of 1-3, b is an integer of 0-2, a+b is an integer of 1-3, and R3 is a monovalent hydrocarbon group.

The first efficient and non-precious nanoparticle catalyst for alkene hydrosilylation with commercially relevant tertiary silanes has been developed. The nickel nanoparticle catalyst was prepared in situ from a simple nickel alkoxide precatalyst Ni(OtBu)2?x KCl. The catalyst exhibits high activity for anti-Markovnikov hydrosilylation of unactivated terminal alkenes and isomerizing hydrosilylation of internal alkenes. The catalyst can be applied to synthesize a single terminal alkyl silane from a mixture of internal and terminal alkene isomers, and to remotely functionalize an internal alkene derived from a fatty acid.
