Usage

Preparation

To a stirred suspension of 1,3,5-tricarbamoylbenzene 1457 (4.6 g, 22.2 mmol) in DMF (35 mL), thionyl chloride (6 mL) was added over a period of 1 h, maintaining the temperature at 60 C°. Stirring at this temperature was maintained for 6 h, during which time complete dissolution occurred. The resulting solution was poured into dilute aq. HCl (100 mL) to decompose unreacted SOCl2, giving a dense white precipitate. This solid was collected by filtration, washed with water until the washings were neutral to litmus, and dried at 120 C° for 14 h. Crystallization from ethanol and acetone yielded the product 1458 as colorless needles (1.50 g, 45%).

Instant Photochromism Caused by Radical Formation in Photocatalytic Decarboxylation of Dihydrothiazole Derivative?

A pair of new enantiomeric compounds, (R)/(S)-1,3,5-benzene-triyl-2,2',2”-tris(4,5-dihydrothiazole-4-carboxylic acid) (H3LRRR and H3LSSS) are synthesized in one step synthetic route with high yield. Instant photochromism has been investigated to elaborate the photocatalytic decarboxylation of the dihydrothiazole derivative by electron paramagnetic resonance spectroscopy (EPR), photoluminescence (PL), FT-IR, high resolution mass spectra, X-ray photoelectron spectroscopy and UV-Vis spectroscopic techniques. The results indicate that the photochromic transformation is originated from the formation of the radical during the photocatalytic decarboxylation of the 4,5-dihydrothiazole-4-carboxylic acid units.

Immobilization of an Aminobisphosphine–PdII Complex over Graphene Oxide: An Efficient and Reusable Catalyst for Suzuki–Miyaura, Ullmann Coupling and Cyanation Reactions

The grafting of an aminobis(phosphine)–PdII complex (PNP–PdII) [PdCl2{(Ph2P)2N(CH2)3Si(OMe)3}] (2) on graphene oxide (GO) has been carried out by a condensation reaction between methoxysilane groups of 2 and hydroxyl groups of GO. The composite material was characterized by FTIR spectroscopy, solid-state 31P NMR spectroscopy, SEM, TEM, XPS and ICP-AES techniques. All these tools support the clean immobilization of compound 2 on GO. The composite material showed high catalytic activity in Suzuki–Miyaura, Ullmann coupling and cyanation reactions. The heterogeneity of the composite was confirmed by a hot filtration test. The immobilized PNP–PdII shows comparable activity to its homogeneous analogue 2. The recycling ability of the catalyst was examined for five consecutive runs, which showed little or no reduction in its catalytic efficiency.

Corresponding amine nitrile and method of manufacturing thereof

The invention relates to a preparation method of nitrile. Compared with the prior art, the preparation method has the characteristics of obvious reduction of the usage amount of ammonia sources, low environmental pressure, low energy consumption, low production cost, high purity and yields of nitrile products, and the like, and can be used for obtaining nitrile with a more complex structure. The invention also relates to a method for preparing corresponding amine with nitrile.
