A supported catalyst for hydrogenating nitro groups of halonitro compounds manufactured from a support, a solvent, and a plurality of organometallic complexes. The organometallic complexes have the formula:
wherein, R
1
-R
6
, are independently an R, OR, OC(═O)R, halogen, or combination thereof, where R stands for an alkyl or aryl group; Y
1
-Y
4
are independently an O, S, N, or P atom; and M is a metal atom. The supported catalysts show much higher selectivity and activity when used to hydrogenate nitro groups on halonitro aromatic compounds than catalyst currently being used for such hydrogenation.
一种用于氢化卤代
硝基化合物的支撑催化剂,由支撑体、溶剂和多种有机
金属配合物制成。有机
金属配合物的
化学式为:其中,R1-R6独立地是R、OR、OC(═O)R、卤素或其组合,其中R代表烷基或芳基基团;Y1-Y4独立地是O、S、N或P原子;M是
金属原子。使用这种支撑催化剂氢化卤代硝基芳香化合物的选择性和活性比目前用于此类氢化反应的催化剂高得多。
