▎ 摘 要
NOVELTY - Product comprises: (a) a support of a carbon material selected from carbon aggregates, carbon fibers, carbon nanotubes, graphene and graphene derivatives; and (b) organometallic compound bound by non-covalent bonds to the support. USE - The product is useful for preparing catalyst (claimed). ADVANTAGE - The catalytic tests show that: (i) the activity of the catalyst is not altered by the presence of the graphene carrier; (ii) the separation between the catalyst and the reaction product is effective; and (iii) the catalyst can be recycled up to ten times without losing activity. DETAILED DESCRIPTION - Product comprises: (a) a support of a carbon material selected from carbon aggregates, carbon fibers, carbon nanotubes, graphene and graphene derivatives; and (b) organometallic compound of formula (I) bound by non-covalent bonds to the support. A=a polycyclic aromatic hydrocarbon; X=a bridging group between A and B' selected from (-CH2-)m, (-CH2-O-)m, (-aryl-CH2-)m or (-CH2-NH- m; n and m=1-4; B'=5- to 8-membered N-heterocyclic group optionally substituted by 1-10C alkyl optionally substituted aryl; (MLn)=a coordinating group; M=a transition metal; and L=a ligand. INDEPENDENT CLAIMS are included for: (1) catalyst comprising the product; and (2) a method of producing the product which involves: (a) reacting a compound of formula A-X-Y' with a compound B' to give a compound of formula A-X-B'; (b) reacting the compound of formula A-X-B' with an organometallic compound (MLn) to obtain the organometallic compound of formula (I): and (c) reacting the product obtained in step (b) with carbon support material. Y'=selected from Cl, Br and I.
