N-Phenyl-4-(2-pyridinyl) sydnone was shown to act as a four-electron donor N,O-ligand in unprecedented coordination complexes featuring three different metallic centers (Co, Cu, and Zn). Starting with various anilines, the use of a ball-mill efficiently enabled the synthesis of N-arylglycines, subsequent nitrosylation and cyclization into sydnones, and further metalation.
N-苯基-4-(2-吡啶基)sydnone在具有三个不同金属中心(Co,Cu和Zn)的前所未有的配位络合物中,可作为四电子供体的N,O-配体。从各种苯胺开始,使用球磨机可以高效地合成N-芳基甘氨酸,随后进行亚硝化和环化成sydnones,并进一步金属化。
