标题:一种双功能铁纳米复合催化剂,可将烯烃高效氧化为酮和1,2-二酮
摘要:我们在此报告了一种双功能铁纳米复合催化剂的制备,其中两个fe-n X催化活性位点磷酸铁和铁的氧化位和路易斯酸位同时被整合到一个分层的n,P-双掺杂多孔碳中.作为一种双功能催化剂,它具有非常好的催化作用,可在较温和的反应条件下使用tbhp作为氧化剂,将烯烃直接氧化裂解为酮或将其氧化为1,2-二酮,具有广泛的底物范围,并具有较高的官能团耐受性.此外,可以很容易地将其回收以进行后续回收,而不会造成明显的活性损失.机理研究表明,烯烃的直接氧化是通过形成环氧化物作为中间体,然后进行酸催化的meinwald重排而产生的,该酮的碳原子短了一个或亲核开环,从而以级联方式反应生成1,2-二酮.

摘要:Fused cyclopentane—4-substituted 3,5-dioxalane lactone compounds useful as an intermediate in the synthesis of prostaglandin analogs are provided. The compounds have the formula A: n nwherein R represents an aryl group such as p-methoxyphenyl.n n This compound can be reacted with a lower alkyl aluminum compound to open the dioxalane ring and reduce the lactone to lactol, without over-reducing to diol. The resulting compound can be functionalized to insert chemical side groups of target prostaglandins, adding the required α-side chain and then the required ω-side chain sequentially and independently of each other. The compounds and process are particularly suitable for preparing lubiprostone.

发明人：COSIMBESCU LELIA
权利人:EASTMAN KODAK CO
摘要:Disclosed is a process for forming a N,N'-diarylquinacridone compound comprising the step of reacting a N,N'-unsubstituted quinacridone compound with a haloaryl compound in the presence of a metal or metal compound to arylate the N and N' positions and form the corresponding N,N'-diarylquinacridone compound. The process is versatile and provides high yields and purity for the synthesis of N,N'-diarylquinacridone compounds.
