  • Photoactive coumarin sulfonate compounds
    申请人:Hoechst Celanese Corporation
    公开号:US05739295A1
    公开(公告)日:1998-04-14
    A new class of 3-diazo-3,4-dihydrocoumarin compounds which are useful as photoactive compounds in a wide variety of applications including photoresists and other opto-electronic applications are disclosed and claimed. Preferred embodiments include 6-sulfonyl-3-diazo-4-oxo-3,4-dihydrocoumarin esters. These compounds exhibit very high photosensitivity in the deep ultraviolet (DUV) region (ca. 250 nm), and therefore, are useful as photoactive compounds in DUV photoresist formulations.

  • Process for preparing coumarin sulfonates
    申请人:Hoechst Celanese Corp.
    公开号:US05773591A1
    公开(公告)日:1998-06-30
    A novel process for preparing sulfonic acid esters and amides of benzo-heterocyclic diazo diketo compounds, such as substituted diazo-4-oxo-3,4-dihydrocoumarins, which are useful synthetic intermediates in a wide variety of applications including photoresists, opto-electronics, agricultural, and pharmaceutical applications is disclosed and claimed. The process comprises the steps of (a) subjecting a substituted benzo-heterocyclic .beta.-keto-enol compound to suitable diazo transfer conditions in the presence of a diazo transfer agent; (b) subjecting the so formed diazo diketo compound to suitable halosulfonation conditions in the presence of a halosulfonation agent; and (c) subjecting the so formed halosulfonyl aromatic compound to suitable substitution reaction in the presence of an alcohol or an amine to form the corresponding sulfonic acid ester or amide of benzo-heterocyclic diazo diketo compound. The compounds formed from the process of the present invention exhibit very high photosensitivity in the deep ultraviolet (DUV) region (ca. 250 nm), and therefore, are useful as photoactive compounds in DUV photoresist formulations.

  • Efficient Synthesis of Five- and Seven-Membered-Ring Heterocycles by Rhodium(II)-Catalyzed [3+2] and [3+4] Cycloaddition of Diazodicarbonyl Compounds with Conjugated Dienes
    作者:Yong Rok Lee、Jae Cheol Hwang
    DOI:10.1002/ejoc.200400452
    日期:2005.4
    Rhodium(II)-catalyzed reactions of diazodicarbonyl compounds with a variety of conjugated dienes have been examined. These reactions provide a simple and rapid route to dihydrofurans and dihydrooxepines with a variety of substituents on the ring. The formation of these products is interpreted in terms of a stepwise mechanism. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)

  • Dichlorination of α-Diazo-β-dicarbonyls Using (Dichloroiodo)benzene
    作者:Graham Murphy、Keith Coffey
    DOI:10.1055/s-0034-1380304
    日期:2015.5
    α-Diazo-β-dicarbonyl compounds were chlorinated using (dichloro)iodobenzene and an activating catalyst. A broad range of reaction rates was observed, which paralleled the relative stability/nucleo­philicity of the diazo compounds. Acyclic diazocarbonyls reacted faster than cyclics, and β-diketones were much faster to react than β-keto esters or β-diesters. Lewis acid activation was used for the first
    使用(二氯)碘苯和活化催化剂氯化α-重氮-β-二羰基化合物。观察到广泛的反应速率,这与重氮化合物的相对稳定性/亲核性平行。无环重氮羰基化合物的反应速度比环状化合物快,而 β-二酮的反应速度比 β-酮酯或 β-二酯快得多。首次使用路易斯酸活化,使我们能够克服化学选择性差的情况。尽管产率从低到好不等,但这种氯化反应再次证明是一种温和有效的卤化策略。
