本文报道了在空气气氛下，在DMSO/H2O中，以铜(OAc)(2)和联吡啶为催化剂，二芳基二碲酸盐与芳基三氟硼酸钾的交叉偶联反应的结果。这种交叉偶联反应是一般的，与二芳基二碲酸盐和芳基三氟硼酸钾进行的具有吸电子、给电子和中性取代基的反应，以很好到很好的产率提供了相应的不对称的二芳基碲化物。
We present here results of the cross-coupling reaction of diaryl ditellurides with potassium aryltrifluoroborate salts using a catalytic amount of Cu(OAc)(2) and bypiridine in DMSO/H2O under air atmosphere. This cross-coupling reaction is general and was performed with diaryl ditellurides and potassium aryltrifluoroborate salts bearing electron-withdrawing, electron-donating and neutral substituents, affording the corresponding unsymmetrical diaryl tellurides in good to excellent yields.
