conditions of the Stille coupling reaction. Derivatives of 2,2′-bipyridine 1-oxides as well as 2,2′:6′,2′′-terpyridine 1′-oxides were synthesised. Oxidation of 2,2′:6′,2′′-terpyridine 1′-oxide with m-CPBA gave 2,2′:6′,2′′-terpyridine 1,1′-dioxide. The crystal structures of 4-nitro-6-bromo-2,2′-bipyridine 1-oxide and 2,2′:6′,2′′-terpyridine 1,1′-dioxide were determined by X-ray structure analysis.
2,6-二溴吡啶N-氧化物和4-硝基-2,6-二溴吡啶N-氧化物在Stille偶联反应条件下用三丁基(吡啶-2-基)锡烷处理。合成了 2,2'-联吡啶 1-氧化物以及 2,2':6',2''-三联吡啶 1'-氧化物的衍生物。用 m-CPBA 氧化 2,2':6',2''-三联吡啶 1'-氧化物得到 2,2':6',2''-三联吡啶 1,1'-二氧化物。通过X射线结构分析确定了4-硝基-6-溴-2,2'-联吡啶1-氧化物和2,2':6',2''-三联吡啶1,1'-二氧化物的晶体结构。
