On August 21, 2020, Cao, Dawei; Chen, Zhangpei; Lv, Leiyang; Zeng, Huiying; Peng, Yong; Li, Chao-Jun published an article.Product Details of 578-58-5 The title of the article was Light-Driven Metal-Free Direct Deoxygenation of Alcohols under Mild Conditions. And the article contained the following:

An efficient metal-free strategy that enabled direct deoxygenation of alcs. to arenes such as RCH2R1 [R = Ph, 2-MeOC6H4, 2-naphthyl, etc.; R1 = H, Me, Ph, etc.] had been developed for the first time, with hydrazine as the reductant induced by light. The features of this protocol were mild reaction conditions, excellent functional group tolerance, and abundant and easily available starting materials, rendering selective deoxygenation of a variety of 1° and 2° alcs., vicinal diols, and β-1 and even β-O-4 models of natural wood lignin. This strategy was also highlighted by its “traceless” and non-toxic byproducts N2 and H2, as readily escapable gases. Mechanistic studies demonstrated di-Me sulfide being a key intermediate in this transformation. The experimental process involved the reaction of 2-Methylanisole(cas: 578-58-5).Product Details of 578-58-5

With the use of KOH/DMSO as the superbase medium, the nucleophilic fluoroarene substitution for C-F bonds was presented. The transformation proceeds smoothly with the use of fluoroarenes such as 2-fluoro-benzamide, 3-fluorobenzaldehyde, 3,4-difluoronitrobenzene, etc. bearing not only electron-withdrawing group, but also electron-donating group and a variety of nucleophiles such as methanol, phenol, dimethylamine, 1H-pyrrole, benzamide, etc.. The double nucleophilic substitution using 3,4-difluoronitrobenzene and nucleophiles bearing ortho-dinucleophilic groups such as 1,2-ethanediol, 1,2-benzenediol, 2-amino-phenol results in the formation of 6-Nitro-2,3-dihydrobenzo[b][1,4]dioxine, 2-Nitrodibenzo[b,e][1,4]dioxine and 2-Nitro-10H-phenoxazine in moderate to good yields.
