In 2019,Green Chemistry included an article by Wu, Zhiqiang; Wang, Gang; Yuan, Shuo; Wu, Dan; Liu, Wanyi; Ma, Baojun; Bi, Shuxian; Zhan, Haijuan; Chen, Xiaoyan. SDS of cas: 120-72-9. The article was titled 《Synthesis of bis(indolyl)methanes under dry grinding conditions, promoted by a Lewis acid-surfactant-SiO2-combined nanocatalyst》. The information in the text is summarized as follows:
An in situ developed Lewis acid-surfactant-SiO2-combined (LASSC) nanocatalyst was used, for the first time, as a green and effective promoting medium for the electrophilic activation of aldehydes RCHO (R = 4-nitrophenyl, 2,4-dichlorophenyl, 3,4-dihydroxyphenyl, etc.) under solvent-free and dry grinding conditions. The advantages of using the LASSC nanocatalyst include avoiding the generation of wastewater containing sodium dodecyl sulfate and the use of toxic reagents, excellent reusability of the catalyst, and obtaining a high yield of bis(indolyl)methanes I (R1 = 6-NO2, 2-Me, 3-Me, etc.). In the experimental materials used by the author, we found 1H-Indole(cas: 120-72-9SDS of cas: 120-72-9)
1H-Indole(cas: 120-72-9) belongs to indole. Indole, also called Benzopyrrole, a heterocyclic organic compound occurring in some flower oils, such as jasmine and orange blossom, in coal tar, and in fecal matter. It is used in perfumery and in making tryptophan, an essential amino acid, and indoleacetic acid (heteroauxin), a hormone that promotes the development of roots in plant cuttings.SDS of cas: 120-72-9
