    Palladium-catalyzed intermolecular transthioetherification of aryl halides with thioethers and thioesters
    (Cambridge : RSC, 2020) Li, Yahui; Bao, Gao; Wu, Xiao-Feng
    Functional group transfer reactions are an important synthetic tool in modern organic synthesis. Herein, we developed a new palladium-catalyzed intermolecular transthioetherification reaction of aryl halides with thioethers and thioesters. The synthetic utility and practicality of this catalytic protocol are demonstrated in a wide range of successful transformations (>70 examples). This catalytic protocol is applicable in carbonylative coupling processes as well, and the first example of carbonylative methylthioesterification of aryl halides has been achieved. Notably, this work also provides an approach to using natural products, such as methionine and selenomethionine, as the functional group sources. This journal is © The Royal Society of Chemistry.

    The Exploration of Aroyltrimethylgermane as Potent Synthetic Origins and Their Preparation
    (Amsterdam [u.a.] : Elsevier, 2019) Yuan, Yang; Zhang, Youcan; Chen, Bo; Wu, Xiao-Feng
    The synthetic utilities of acylgermanes are surprisingly rarely explored compared with their analogues. In this communication, the survey of aroyltrimethylgermane as potent synthetic origins has been studied. A variety of novel chemical transformations have been realized, including using the acylgermane group as a directing group in Rh-catalyzed aromatic C-H alkenylation reaction and Ir-catalyzed aromatic C-H amidation reactions. Additionally, a general approach for acylgermanes preparation has been established as well. The catalytic system proceeds effectively in the presence of Pd(OAc)2/BINOL-based monophosphite (L11) and allows for the straightforward access to a wide range of functionalized acylgermanes in high yields. © 2019 The Author(s)Catalysis; Organic Synthesis; Organic Reaction; Chemical Synthesis © 2019 The Author(s)
