SDS of cas: 3340-78-1, New Advances in Chemical Research, May 2021. Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 3340-78-1, Name is 2-Phenyl-1,2,3,4-tetrahydroisoquinoline,introducing its new discovery.

Two new push-pull molecules with imidazole-4,5-dicarbonitrile acceptor, thiophene and 2-methoxythiophene donors with potential use in photoredox catalysis were designed and prepared. The synthesis started from commercially available imidazole-4,5-dicarbonitrile and its bromination and N-methylation. Subsequent Suzuki-Miyaura cross-coupling with (5-methoxy)thiophene-derived boronic acids afforded target push-pull derivatives. Beside common analytical methods, the molecular structure of 5-methoxythiophen-2-yl derivative has also been verified by X-ray analysis. DSC analyses showed remarkable thermal stabilities of both target derivatives with Tm and TD values above 150 and 270 C, respectively. Fundamental properties and extent of the intramolecular charge-transfer were further studied by UV-VIS absorption spectra and DFT calculations. Fundamental photoredox properties of target imidazole derivatives were elucidated. Both push-pull molecules were preliminary tested as photoredox catalysts in cross-dehydrogenative coupling reaction between tetrahydroisoquinoline and nitromethane and the results were compared with those obtained by pyrazine-2,3-dicarbonitrile-derived catalyst.

In a Article，once mentioned of 78183-55-8

The use of the tetrahydroisoquinoline scaffold is well documented in biologically active compounds. However, reports of the utilisation of tetrahydroisoquinoline compounds in asymmetric catalysis are limited. The synthesis of novel diamine ligands possessing the tetrahydroisoquinoline (tetrahydroisoquinoline) backbone and evaluation of their activity in the asymmetric transfer hydrogenation of acetophenone are presented. The diamine ligands in conjunction with i-PrOH as the hydrogen source and [RhCl2(Cp*)]2 as the metal precursor proved to be the most effective of the tetrahydroisoquinoline derivatives for this catalytic system. Water was found to have a profound influence on the enantioselectivity of the reaction. Optimisation of the amount water, i-PrOH and catalytic loading content rendered the best result of 70% enantioselectivity for the (S)-1-phenylethanol isomer product.

Visible light induced oxidative C-H functionalisation of tertiary amines catalysed by the combination of graphene oxide and Rose Bengal was developed. This reaction avoids the use of stoichiometric amounts of peroxy compounds as terminal oxidants. This reaction is useful for tri-alkyl amines including chiral tertiary amines.

Aerobic oxidation of 2-aryl-1,2,3,4-tetrahydroisoquinolines was achieved photocatalytically using chalcogenorosamine photocatalysts and LED irradiation. The photocatalytic aza-Henry reaction between these substrates and nitromethane was more efficient with selenorosamine and tellurorosamine photocatalysts than with thiorosamine and rosamine photocatalysts, corresponding to the propensity of the photocatalysts to generate singlet oxygen (1O2). Appropriately, yields for the photocatalytic aza-Henry reaction were greatly reduced when the reactions were conducted under a nitrogen atmosphere. The 2-aryl-1,2,3,4-tetrahydroisoquinolines were oxidized to the corresponding 2-aryl-3,4-dihydroisoquinolones 13a-13c with selenorosamine and tellurorosamine photocatalysts in 2% aqueous acetonitrile. Di-2-aryl-1,2,3,4-tetrahydroisoquinolin-1-yl peroxides 14a and 14b were shown to be intermediates in this reaction. Thiorosamine photocatalysts, which do generate 1O2 upon irradiation, did not give 2-aryl-3,4-dihydroisoquinolones. These results suggested that the exciplex between 1O2 and the chalcogen atom of the chalcogenorosamines (the corresponding pertelluoxide, perselenoxide, or persulfoxide) and/or the hydrated perchalcogenoxide [hydroxy (perhydroxy)tellurane, -selenane, or -thiane] might be an active oxidant in the formation of 13a-13c. Computational methods were employed to provide support for the observed photocatalytic reactivity of the tellurorhodamine and selenorhodamine chromophores compared to the thiorosamine chromophores. deltaG values were determined for the oxidation and hydration of 10-Te, 10-Se, and 10-S for formation of perchalcogenoxides and hydroxyl(perhydroxy)chalcogenanes, respectively. Calculations indicate formation of the pertelluroxide perselenoxide, and persulfoxide exciplex intermediates are energetically favorable. Hydration of the exciplexes of 10-Te and 10-Se have similarly small deltaG of -3.49 and 4.51 kcal/mol, respectively. However, a significantly higher deltaG value of +22.4 kcal/mol is observed for the hydration of 10-S, which suggests that this reactive intermediate is not readily formed.

In some cases, the catalyzed mechanism may include additional steps.In a article, 166591-85-1, molcular formula is C15H19NO4, introducing its new discovery.

Recent visible-light photoredox catalyzed C(sp3)-C(sp2) cross-coupling provides a novel transformation to potentially enable the synthesis of medicinal chemistry targets. Here, we report a profiling study of photocatalytic C(sp3)-C(sp2) cross-coupling, both decarboxylative coupling and cross-electrophile coupling, with 18 pharmaceutically relevant aryl halides by using either Kessil lamp or our newly developed integrated photoreactor. Integrated photoreactor accelerates reaction rate and improves reaction success rate. Cross-electrophile coupling gives higher success rate with broad substrate scope on alkyl halides than that of the decarboxylative coupling. In addition, a successful application example on a discovery program demonstrates the efficient synthesis of medicinal chemistry targets via photocatalytic C(sp3)-C(sp2) cross-coupling by using our integrated photoreactor.
