6-Nitro-1H-indole (cas: 4769-96-4) belongs to indole derivatives. The indole subunit is an almost ubiquitous component of biologically active natural products, and its study has been the focus of research for decades. Indole plays a fundamental role for QS in E. coli, being one of the signal molecules responsible for the transcription of a variety of genes (gabT, and tnaB ASTD). Electric Literature of C8H6N2O2

Magnetically recyclable Sm2Co17/Cu catalyst to chemoselectively reduce the 3-nitrostyrene into 3-vinylaniline under room temperature was written by Ma, Zhenhui;Liu, Hu;Yue, Ming.

Using non-noble metal catalysts to chemoselectively reduce the 3-nitrostyrene into 3-vinylaniline is extremely attractive due to the important applications of aromatic amines. However, the separation and recycle of catalytic particles to sustainably catalyze are still challenging on account of their small size. In this communication, we report a novel magnetically recyclable catalyst of Sm2Co17/Cu to chemoselectively reduce 3-nitrostyrene into 3-vinylaniline by activating ammonia borane (AB) to yield hydrogen. The Sm2Co17, composited of 180 nm Sm2Co17 nanomagnet and 10 nm Cu catalyst nanoparticles, shows a high conversion (98%) and a high selectivity (99%) for 3-nitrostyrene under ultrasonic concussion. More importantly, they are easily collected by self-separation method without any magnetic field. As a consequence, the excellent recyclable feature is acquired even underwent 10 cycles. Our approach provides a green strategy to synthesize magnetically recyclable catalysts. In the experiment, the researchers used many compounds, for example, 6-Nitro-1H-indole (cas: 4769-96-4Electric Literature of C8H6N2O2).
