Electrochemical initiation by sulfur dioxide of radical-chain trifluoromethylation processes of thiophenols with bromotrifluoromethane
摘要:
Sulfur dioxide may serve as an efficient catalyst for the electrochemical trifluoromethylation of thiophenols by Freon F13B1 (CF3Br), which enables implementation of trifluoromethylation in an energy-saving radical-chain regime.

Perfluoroalkylation of aliphatic, aromatic and heterocyclic thiols by perfluoroalkyliodides in the presence of Et3N appears to occur spontaneously under daylight or the usual laboratory lighting conditions at 20–22 °C and is complete in 10–15 min to 2–3 h. An exception to this rule are thiols with a low nucleophilicity. The reaction is accompanied by thiol oxidation (2%–3%) and depends directly on
Provided herein is a compound of Formula I, or a salt thereof,
wherein R1 is a moiety having the following structure:
wherein Z is selected from the group consisting of O and N; X is selected from the group consisting of a bond, NH, and C(O)NH; and A is selected from the group consisting of substituted aryl and substituted heteroaryl. Compounds of Formula I are useful as opioid receptor agonists. Because the compounds exhibit relatively low levels of β-arrestin recruitment, they do not produce the negative side effects commonly associated with morphine-derived compounds.
本文提供的是式 I 的化合物或其盐、
其中 R1 是具有以下结构的分子:
其中 Z 选自由 O 和 N 组成的组;X 选自由键、NH 和 C(O)NH 组成的组;A 选自由取代芳基和取代杂芳基组成的组。式 I 的化合物可用作阿片受体激动剂。由于这些化合物的β-阿司匹林招募水平相对较低,因此不会产生吗啡衍生化合物常见的不良副作用。
Cu-mediated oxidative trifluoromethylthiolation of arylboronic acids with (bpy)CuSCF3
An efficient trifluoromethylthiolation reaction of arylboronic acids with (bpy)CuSCF3 in the presence of oxygen at room temperature is described. This method produces a variety of aryl trifluoromethylthioether derivatives in good to high yield. The mechanism of this trifluoromethylthiolation is discussed as well. (C) 2017 Elsevier B.V.
