Nitroacenaphthene as a New Photocatalyst for the Synthesis of Sulfonyl Amidines was written by Jian, Yong;Chen, Ming;Yang, Chao;Xia, Wujiong. And the article was included in Synthesis in 2019.SDS of cas: 777-44-6 This article mentions the following:
A small mol., namely nitroacenaphthene, is reported for the first time as a recyclable visible-light photocatalyst for the construction of the C=N bond from sulfonyl azides RS(O)2N3 (R = Pr, 4-bromophenyl, naphthalen-1-yl, thiophen-2-yl, etc.) and amines R1N(R2)(R3) (R1 = H, Me, Et, n-Pr; R2 = Et, n-Pr, i-Pr, n-Bu; R3 = Me, Et, n-Pr, i-Pr, n-Bu). This scalable, site-selective protocol provides a convenient way to access various sulfonyl amidines (E/Z)-RS(O)N=CHN(R2)(R3) under mild conditions. Two reaction pathways are proposed according to different transformation patterns. In the experiment, the researchers used many compounds, for example, 3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6SDS of cas: 777-44-6).
3-(Trifluoromethyl)benzene-1-sulfonyl chloride (cas: 777-44-6) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.SDS of cas: 777-44-6
