Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. Electric Literature of 3340-78-1, 3340-78-1, Name is 2-Phenyl-1,2,3,4-tetrahydroisoquinoline, molecular formula is C15H15N. In a Article，once mentioned of 3340-78-1

Visible-light-induced, eosin Y catalyzed aerobic oxidative alpha-C(sp3)-H thiocyanation of tertiary amines is reported. The reaction proceeds through visible-light-induced in situ generation of the iminium ion followed by attack of -SCN nucleophile. This is the first example of visible-light-initiated formation of C(sp3)-S bond employing organo-photoredox catalysis. Mild reaction conditions and use of air and visible light as the greenest and sustainable reagents at room temperature are the salient features of the protocol.

In chemical reaction engineering, 78183-55-8, simulations are useful for investigating and optimizing a particular reaction process or system. 78183-55-8, Name is (S)-Methyl 1,2,3,4-tetrahydroisoquinoline-3-carboxylate hydrochloride, molecular formula is C11H14ClNO2. In a Article，once mentioned of 78183-55-8

We report herein the synthesis of new dioxopiperazine isoquinolines using the Pictet-Spengler cyclisation. Our synthetic strategy for the preparation of two new compounds (5, 6), with a tetrahydro-6H-pyrazino[1,2-b]isoquinoline-1,4-dione moiety was developed in only four steps. To understand better the crucial step of the synthesis reported here, theoretical calculations using semiempirical (PM3), ab initio and DFT computations were carried out on a reduced system model. The structure of chlorohydrate water solvate of tetrahydro (2-piperidinylethyl)-6H-pyrazino [1,2-b]isoquinoline-1,4-dione (6·HCl·2H2O) was determined by X-ray diffraction. Theoretical calculations (RHF/3-21G and RB3LYP/6-31G(d)) were also performed for compound 6 neutralised with a chloride ion.

A novel method for the synthesis of alpha-aminonitrile through visible-light-induced oxidative cyanation of N-aryltetrahydroisoquinoline with potassium thiocyanate has been developed. The process does not require the use of a photocatalyst, transition metal reagent, strong oxidizing agent, or toxic cyano-containing compound, which makes the reaction simple and green.

Cross-dehydrogenative-coupling reaction has long been recognized as a powerful tool to form a C-C bond directly from two different C-H bonds. Most current processes are performed by making use of stoichiometric amounts of oxidizing agents. We describe here a new type of reaction, namely cross-coupling hydrogen evolution (CCHE), with no use of any sacrificial oxidants, and only hydrogen (H2) is generated as a side product. By combining eosin Y and a graphene-supported RuO2 nanocomposite (G-RuO2) as a photosensitizer and a catalyst, the desired cross-coupling products and H 2 are achieved in quantitative yields under visible light irradiation at room temperature.
