▎ 摘　　要

NOVELTY - Silylation catalyst comprises carbon structure containing carbon nanotubes, carbon nanofibers, carbon nano hair, fullerene, carbon nanocone, carbon nanohorn, carbon nanorods, activated carbon, black smoke, artificial graphite, graphene, graphite and/or graphene nanoflot, and organic boron compound. The carbon structure and the organic boron compound are connected by pi - pi bond. USE - The silylation catalyst is useful for synthesis of intermediates. ADVANTAGE - The silylation catalyst has excellent catalytic activity without using expensive metal, excellent selectivity, high functional group resistance in reduction reaction, and chemical selectivity to react only with specific functional group of compound having multifunctional group, improves purity of compound, and is economical. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) producing silylation catalyst, comprising (a) preparing mixed solution of carbon structure and organic boron compound, and (b) filtering the mixed solution, washing and drying the obtained crude product to prepare catalyst; and (2) producing silylated compound, comprising reacting silyl compound with compound having a functional group including carboxylic acid group, aldehyde group, ketone group, hydroxy group and epoxide group to prepare a silylated compound.
