摘要:
Provided are: a (meth)allylsilane compound that is chemically bonded to various alcohol derivatives including polyol derivatives such as saccharides, is a raw material that is used to cause a substrate to express functionalities such as a defogging property and separation characteristics for column chromatography, can be easily prepared, is easily purified, and is stable and easy to handle, and a functional material in which those functionalities are expressed, while silyl group-containing groups are conveniently carried at a high density on the surface of the substrate, by using the (meth)allylsilane compound as a silane coupling agent for silane-coupling to the substrate. The (meth)allylsilane compound comprises a (meth)allylsilyl group-containing alkyl group or a (meth)allylsilylalkyl group-containing aralkyl group that is bonded to an alcohol derivative. In the functional material, the silane coupling agent is ether-bonded to surface hydroxyl groups exposed on a substrate through the surface hydroxyl groups by silane coupling to have an ether bond on the functional material.
摘要:
A polymer having bis(diphenylphosphino)binaphthyl groups that can be used as a catalyst for an addition reaction, especially an asymmetric 1,4-addition reaction, or a reduction reaction, especially an asymmetric reduction reaction, and that can be easily recovered and recycled. The polymer having the bis(diphenylphosphino)binaphthyl groups is one resulting from repetition of a racemic or optically active 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl compound substituted at 5-position thereof with an unsaturated terminal of one (meth)acryloyl group of a compound having multiple (meth)acryloyl groups, that another 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl compound of a next unit is substituted at 5'-position thereof with an unsaturated terminal of another (meth)acryloyl group of the compound having multiple (meth)acryloyl groups so as to have a molecular weight of 1500 to 10000. The reduction catalyst comprises this polymer and a transition metal.
