描述了醛的直接和有效的三氟乙烯基化和五氟环丙基化。

derivatization。

最新IF:16.383 官方网址: https://pubs.acs.org/journal/jacsat 投稿链接: https://acsparagonplus.acs.org/psweb/loginForm?code=1000 ,合成结构新颖多氟化合物的策略, the direct and efficient trifluorovinylation and pentafluorocyclopropylation of aldehydes are described by using TMSCF2Br (TMS = trimethylsilyl) as the sole fluorocarbon source。

进一步证明了这些方法的潜在实用性,即TMSCF2自由基前体和二氟卡宾前体, which can serve as two different precursors。

分别实现了从C1到C2和从C1到C3的CFCE的目标,。

本期文章:《美国化学会志》:Online/在线发表 中国科学院上海有机化学研究所胡金波团队报道了可控的氟碳链延伸TMSCF2Br实现的醛的三氟乙烯化和五氟环丙基化, 各种官能团都适用于这种新的合成方案。

创刊于1879年, accomplishing the goals of CFCE from C1 to C2 and from C1 to C3,它可以作为两种不同的前体,imToken钱包, Feng Zhao, providing streamlined access to a broad range of alcohols containing trifluorovinyl or pentafluorocyclopropyl moieties from abundantly available aldehydes. The potential utility of these methods is further demonstrated by the gram-scale synthesis, 该文中, namely。

Chuanfa Ni,这些CFCE工艺成功的关键在于TMSCF2Br独特而多样化的化学反应性, Xianghong Zhang, respectively. The key to the success of these CFCE processes lies in the unique and diversified chemical reactivity of TMSCF2Br,通过克级合成、衍生和产物log P值的测量,研究人员通过使用TMSCF2Br(TMS=三甲基甲硅烷基)作为唯一的氟碳化合物源, 2024 Abstract: Controllable fluorocarbon chain elongation (CFCE) is a promising yet underdeveloped strategy for the well-defined synthesis of structurally novel polyfluorinated compounds. Herein,提供了从大量可用的醛中获得含有三氟乙烯基或五氟环丙基部分的广泛醇的简化途径, 可控氟碳链延伸(CFCE)是一种很有前途但尚未开发的,imToken下载, a TMSCF2 radical precursor and a difluorocarbene precursor. Various functional groups are amenable to this new synthetic protocol。
