  4-Methyloxazole and 4,4-dimethyl-2-oxazoline were treated with n-butyllithium and trimethyltin chloride to give the corresponding 2-trimethylstannyl derivatives which in the presence of tetrakis(triphenylphosphine)palladium(0) as a catalyst undergo cross-coupling reactions with various aryl and heteroaryl halides to give 2-aryl and 2-heteroaryl oxazoles and oxazolines in high yields.

  C–H arylations of oxazolines were accomplished with a well‐defined palladium catalyst derived from a secondary bisdiamantyl phosphine oxide. The single‐component secondary phosphine oxide (SPO)‐palladium complex enabled C–H activations with aryl bromides and challenging aryl chlorides in the absence of directing groups, setting the stage for the step‐economical synthesis of pybox ligands under racemization‐free

  恶唑啉的C–H芳基化反应是使用衍生自仲双双金刚烷基氧化膦的明确定义的钯催化剂完成的。单组分仲氧化膦（SPO）-钯配合物可在没有引导基团的情况下用芳基溴化物和具有挑战性的芳基氯化物进行C-H活化，为在无消旋反应条件下逐步经济地合成pybox配体奠定了基础。
