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
