The method for producing a surface-modified base material according to the present invention includes a step of bringing a base material having a polar group present on a surface thereof into contact with a hydrosilane compound having a molecular structure A and having a Si—H group composed of a silicon atom of the molecular structure A and a hydrogen atom bonded to the silicon atom in the presence of a borane catalyst so as to allow a dehydrocondensation reaction to take place between the base material and the compound, thereby forming the base material surface-modified with the molecular structure A. This production method is capable of surface-modifying a base material at a lower temperature in a shorter time than conventional methods and allows a wide variety of options for the form, type, and application of the base material, the mode of the modification reaction, and the type of the molecular structure with which the base material is surface-modified.
We established a highly enantioselective Si-H insertion reaction to construct chiral centers at the carbon and silicon atoms, using Ru(II)-Pheox catalyst. The catalytic asymmetric Si-H insertion reaction of [small alpha]-methyl-[small alpha]-diazoesters proceeded...
An efficient method for the dehydrogenative coupling of silanes with alcohols under photocatalysis was developed. The reaction proceeded in the presence of Ru(bpy)3Cl2 (0.5 mol%) under visible light irradiation in acetonitrile at room temperature. The developed methodology was also applicable for the synthesis of silanols using water as a coupling partner.

dodecacarbonyl catalyst (Ru3(CO)12) allows very efficient and convenient access to functionalized silsesquioxanes (SQs) containing siloxane moiety (Si–O–Si) via dehydrogenative coupling of POSS-silanols with hydrosilanes. With the aid of SiH-containing silsesquioxanes, an unprecedented one-pot procedure has been revealed, and the usefulness of this approach was demonstrated by the synthesis of various derivatives
