On August 30, 2019, Yalcin, Ergin; Duyar, Halil; Cakmaz, Deniz; Sahin, Ertan; Seferoglu, Zeynel published an article.Safety of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile The title of the article was The synthesis of blue emitting 3-Amino-1-hetarylfluorenes and their unprecedented alkylated derivatives. And the article contained the following:

Novel 3-Amino-1-hetarylfluorene derivatives have medicinal uses and challenging transformation in organic synthesis have been synthesized via decyanation process. Surprisingly, the alkylated compounds derived from 3-Amino-1-hetarylfluorenes were obtained via further nucleophilic substitution to the 9-C and 3-N positions of the fluorene ring because of the harsh reaction condition employed. The synthesized compounds were characterized by spectroscopic techniques as well as X-ray single crystal diffraction anal. This new family of blue emitting fluorene derivatives have low to moderate quantum yields (the largest value of 蠁F = 0.52 for compound 15). The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Safety of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile

R2R3NCH:CR1CR:CXCN [R,R1 = alkyl, aryl; RR1 = (CH2)n (n = 3-5); R2, R3 = alkyl, aryl; R2R3 = (CH2)4, (CH2)5, (CH2)2O(CH)2; X = CN, carbonyl such as acyl, alkoxycarbonyl, H2NCO, NO2, aryl], useful as synthons for pharmaceuticals were prepared by reaction of R1CH2CR:CXCN with HC(OR4)3 (R4 = alkyl) and HNR2R3 in the presence of acidic condensation agent by 8 methods. A mixture of 2-O2NC6H4CO2H and 0.01 mol HNPhMe was treated with 0.015 mol HC(OEt)3 and 0.01 mol Me2C:C(CN)2 and the mixture refluxed 30 min. to give 65% MePhNCH:CHCMe:C(CN)2.

On March 31, 2000, Asiri, Abdullah Mohamed published an article.SDS of cas: 2510-01-2 The title of the article was Synthesis, characterizations and absorption spectral properties of new styryl dyes derived from 1-dicyanomethyleneindane. And the article contained the following:

The synthesis and the absorption properties of methine dyes formed by the Knoevenagel condensation of aromatic aldehydes with 1-(dicyanomethylene)indan afforded a novel series of dyes absorbing in the region of 490-593 nm. The substituents on the aromatic aldehyde have remarkable effects on the visible absorption maxima of the new dyes. Indole-3-carboxaldehyde gave a blue dye. The introduction of dicyanomethylene group into 1-indanone causes a large bathochromic shift of the visible absorption maxima of the new dyes when compared with the same dye obtained from 1-indanone itself. Steric effects cause even more of a bathochromic shift compared dyes having substituents in the ortho position and the same dyes having the same substituents in the para position. Increasing the solvent polarity had pronounced effects on the absorption maxima. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).SDS of cas: 2510-01-2

On April 30, 2002, Almonasy, Numan; Nepras, Milos; Burgert, Ladislav; Lycka, Antonin published an article.Synthetic Route of 2510-01-2 The title of the article was Synthesis, visible absorption spectra and application properties of disperse dyes derived from 1-indanylidenemalononitrile. And the article contained the following:

Disperse dyes derived from 1-indanylidenemalononitrile and aromatic aldehydes were prepared and characterized. The purity of the dyes was checked by TLC and elemental anal.; the structures were confirmed by 1H and 13C NMR spectra. The relationships among dye structures and absorption characteristics and solvent polarity effects were investigated. The full optimized geometry was computed by the AM1 method and the theor. characteristics of electronic transitions were studied by PPP-MO, CNDO/S, and INDO/S procedures. Due to possible application of the dyes to polyester fiber, the coloristic characteristics were determined as well. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Synthetic Route of 2510-01-2

On November 30, 2001, Asiri, Abdullah Mohamed published an article.Synthetic Route of 2510-01-2 The title of the article was Organometallic dyes: Part 1. Synthesis of orange to cyan dyes based on donor-conjugated-acceptor chromogenes using ferrocene as the donor group. And the article contained the following:

A novel series of organometallic donor-conjugated-acceptor dyes derived from ferrocene as the donor group have been synthesized via the Knoevenagel reaction of ferrocene carboxaldehyde and various active methylene compounds to give a range of dyes ranging from orange to blue-green in color. The most bathochromic dye is that derived from dialkyl thiobarbituric acid and the least is that derived from the tetralone. The dyes showed an unusual neg. solvatochromism as the solvent polarity increased. All dyes synthesized are expected to have some non-linear optical properties, as evidenced from the pronounced solvatochromism. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Synthetic Route of 2510-01-2
