  通过Pd催化的二有机基碲化物的脱酯均偶联反应进行碳-碳键形成反应

  摘要：

  报道了一种用于构建Csp-Csp，Csp 2 -Csp 2和Csp 3 -Csp 3键的简单且高效的方法。对称的二芳基碲化物经历脱酯均偶联，得到对称的联芳基产物。该反应在Ag 2 O和Na 2 CO 3的存在下使用PdCl 2作为催化剂在环境温度下进行。类似地，二苄基碲化物和双（苯基乙炔基）碲化物的脱酯均偶联分别得到联苄基和共轭二炔。

  Abstract A new method of Sonogashira coupling reactions between diorganyl tellurides and terminal alkynes is reported. The coupling reactions are performed using Pd(dppf)Cl2 as a catalyst, CuI as a co-catalyst in the presence of K2CO3 in DMSO. The reactions are carried out at room temperature and completed within 2 h when phenyl acetylene is used as a terminal alkyne. For aliphatic terminal alkynes

  摘要 报道了一种二有机碲化物与末端炔烃之间Sonogashira偶联反应的新方法。偶联反应使用 Pd(dppf)Cl2 作为催化剂，CuI 作为助催化剂，在 K2CO3 的 DMSO 中进行。当苯乙炔用作末端炔烃时，反应在室温下进行并在2小时内完成。对于脂肪族末端炔烃，例如 1-己炔和 1-辛炔，完成反应需要升高的温度和更长的反应时间。该方法产生了适用于二芳基、二乙烯基和二炔基碲化物但不适用于二烷基碲化物的 Sonogashira 偶联产物的良好收率。图形概要

  A highly efficient new protocol for C-Te bond formation leading to symmetrical diaryl tellurides has been developed. The synthesis employed aryl iodides and elemental tellurium as starting materials in the presence of KOH. It is a one-pot reaction without using any catalyst. Utilizing this new protocol, a variety of aryl and heteroaryl iodides are reacted with elemental tellurium to afford the corresponding diaryl tellurides in good to excellent yields.

• Formation of an emissive telluroxide promoted by Hg2+ in aqueous environment: A new naked-eye and ratiometric rhodamine dimer fluorescent mercury(II) probe

  A new chemosensor based on tellurium-rhodamine B (TRB) for the fast and selective detection of Hg2+ in aqueous medium was designed and synthetized in only two steps from a symmetrical organic telluride and rhodamine B. The structure of TRB was determined by RMN, HRMS and IR and its photophysical properties were determined in MeCN/H2O 75:25 v/v. TRB is able to detect Hg2+ in solutions diluted until 1.71 mu mol/L and containing until 75% of water in it. In the presence of Hg2+, TRB presents an intense pink color with maximum absorption in 558 nm (log epsilon = 4.93) and a strong fluorescence emission with maximum intensity in 582 nm (Phi = 0.17). The detection of Hg2+ by TRB occurs by the oxidation of the tellurium promoted by Hg2+, where a redox mechanism was proposed. Even the detection of Hg2+ occurring by the oxidation of tellurium, TRB presented a high selectivity for Hg2+, even when several ROS (H2O2, KNO2, NaOCl, NaONOO e KO2) were submitted to the screening.
