In present work, we have described the use of polyamine solid supported GN3 as catalyst in organic transformations using 1H-indole-3-carbaldehyde. To the best of our knowledge, reports for the synthesis of chromene substituted at 3C position of indole are extremely rare in the literature. The polyamine functionalized immobilized silica (GN3) was found to be an excellent catalyst for synthesis of novel 2-amino-4-(1H-indol-3-yl)-5-oxo-4,5-dihydropyrano[3,2-c]chromene-3-carbonitrile derivatives and Knoevenagel condensation. Catalyst GN3 was able to furnish excellent yield for a wide range of products. Moreover, the catalyst was reusable and reused for several times without loss of its catalytic activity. The experimental process involved the reaction of 2-((1H-Indol-3-yl)methylene)malononitrile(cas: 75629-62-8).Recommanded Product: 2-((1H-Indol-3-yl)methylene)malononitrile

On February 12, 2015, Motiyenko, Roman A.; Margules, Laurent; Alekseev, Eugen A.; Guillemin, Jean-Claude published an article.Safety of 2-Aminomalononitrile 4-methylbenzenesulfonate The title of the article was High-Resolution Millimeter Wave Spectroscopy and Ab Initio Calculations of Aminomalononitrile. And the article contained the following:

The HCN trimer aminomalononitrile (H2NCH(CN)2, AMN) is considered as a key compound in prebiotic chem. and a potential candidate for detection in the interstellar medium. In this view, we studied the rotational spectrum of AMN in the 120-245 GHz frequency range. The spectroscopic work was augmented by high-level ab initio calculations The calculations showed that between two existing rotamers, sym. and asym., the most stable is the asym. conformation, and it is the only conformation observed in the recorded spectra. The sym. conformation is 6.7 kJ/mol higher in energy and thus has a very low Boltzmann factor. The anal. of the rotational spectra of the A conformation has shown that the observed lines exhibit a doublet or quartet structure owing to two large-amplitude motions, C-N torsion and amino group inversion. To study the large-amplitude motions in detail, we calculated a two-dimensional potential energy surface and determined the barrier heights for the torsion and inversion, Vt = 12.5 kJ/mol and Vi = 19.1 kJ/mol. About 2500 assigned rotational transitions in the ground vibrational state were fitted within exptl. accuracy using the reduced axes system Hamiltonian. The set of obtained spectroscopic parameters allows accurate calculation of transition frequencies and intensities for an astrophys. search of AMN. The experimental process involved the reaction of 2-Aminomalononitrile 4-methylbenzenesulfonate(cas: 5098-14-6).Safety of 2-Aminomalononitrile 4-methylbenzenesulfonate

Estrada, Leandro A.; Frances-Monerris, Antonio; Schapiro, Igor; Olivucci, Massimo; Roca-Sanjuan, Daniel published an article in 2016, the title of the article was Mechanism of excited state deactivation of indan-1-ylidene and fluoren-9-ylidene malononitriles.Reference of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile And the article contains the following content:

Herein, we report complementary computational and exptl. evidence supporting the existence, for indan-1-ylidene malononitrile and fluoren-9-ylidene malononitrile, of a non-radiative decay channel involving double bond isomerization motion. The results of UV-Vis transient absorption spectroscopy highlight that the decay takes place within hundreds of picoseconds. In order to understand the related mol. mechanism, photochem. reaction paths were computed by employing multiconfigurational quantum chem. The results indicate that the excited state deactivation occurs via concerted double bond twisting of the dicyanovinyl (DCV) unit coupled with a pyramidalization of its substituted carbon. It is also shown that the observed differences in the excited state lifetimes when passing from indan-1-ylidene malononitrile to fluoren-9-ylidene are associated with the change in the topog. of the conical intersection driving the decay from intermediate to sloped, resp.

Wang, Hung-Kai; Chio, Yu-Lun; Pallikonda, Gangaram; Wu, Hsyueh-Liang; Su, Haw-Lih; Hsieh, Jen-Chieh published an article in 2020, the title of the article was Copper-catalyzed dual cyclization for the synthesis of quinindolines.Category: nitriles-buliding-blocks And the article contains the following content:

A synthetic approach to quinindoline derivatives I (R = H, F, CF3, OMe, ; R1 = H, F, Me, OMe, NMe2; R2 = H, F, CF3, OMe; R3 = H, F, Cl, Me, NMe2, N(n-C4H9)2, OMe; R4 = H; RR1 = R2R3 = -OCH2O-; R3R4 = -CH:CH-CH:CH-) by the Cu-catalyzed dual cyclization has been developed. This catalytic reaction is a practical method for the systematic synthesis of quinindoline core structure I, which contains a limited-step synthetic strategy and can tolerant a wide variety of substituents. In addition, the mechanistic study reveals that the reaction initiates from a Lewis acid accelerated addition of aniline to nitrile and provides the indole substructure, and then the subsequent Cu-catalyzed C-N coupling reaction furnishes the quinoline subunit and affords the quinindoline structure I.
