【摘要】 合成了12种PAMAMSA(1～6G) M(PAMAM为聚酰胺 胺,SA为水杨醛,G为代数,M分别为Fe3+,Co2+离子)树枝状高分子催化剂.在101 325kPa、70℃和无溶剂条件下,这些催化剂对环己烯分子氧氧化反应的催化效果良好.反应以7 氧杂二环[4,1,0]己烷(1),2 环己基 1 醇(2),2 环己基 1 酮(3)和7 氧杂二环[4,1,0]己烷 2 酮(4)为主要产物.其中产物7 氧杂二环[4,1,0]己烷 2 酮(4)为此类氧化反应中首次报道的新产物.更多还原

【Abstract】 12 dendritic complexes of PAMAM SA(1～6 G)-M(where PAMAM=polyamidoamine , SA=salicyaldehyde, G=generation, M=Fe-(3+_ and Co-(2+_ ion s) c omplexes are synthesized. All the complexes show promising catalytic activities for the oxidation of cyclohexene under 70℃ and 101.325 kPa pressure of molecular oxygen. The oxidation gives 2-cyclohexen-1-ol (1) , 2-cyclohexen-2-one (2), 7-oxabicyclo([4.1.0]_heptane(3)and 7-oxabicyclo[4.1.0]heptan-2-one(4)as major products. The factors which affect the oxidation are also primarily discussed.更多还原
