聚合物键联钴卟啉的合成及其催化作用

Synthesis of Polymer-Bonded Cobalt-Porphyrin Complex and as an Oxidation Catalyst for Propanethiol

合成了 5 -对羟苯基 - 1 0 ,1 5 ,2 0 -三 (对甲氧苯基 )卟啉 (1 )及其钴配合物 (2 )。将(1 )与氯甲基化聚苯乙烯树脂键合得聚合物键联卟啉 (3) ,(3)与钴离子络合得聚合物键联钴卟啉 (4) ,考察了 (4)对丙硫醇的催化氧化作用。对卟啉化合物进行了 IR、UV测定和元素分析。对丙硫醇氧化产物作了 HPL C、UV、IR和 MS分析。

p Hydroxybenzyl) 10,15,20 tri( p methoxyphenyl) porphyrin (1) and its cobalt complex (2) were synthesized. Polymer bonded porphyrin (3) was prepared by attaching functionalized compound (1) to chloromethylated polystyrene resin via ether linkage. Polymer bonded cobalt porphyrin complex(4) was then obtained by coordinating cobalt ion to the polymer bonded porphyrin compound (3). The catalytic activity of compound (4) for the oxidation of propanethiol was studied. The chemical structures of porphyrin compounds were identified by IR and UV spectra as well as elemental analysis. The composition of the product was also identified by HPLC、UV、IR and MS.
