Phosphorus-based macrocycles with acetylenic scaffolds have been built from acetylene-substituted phosphane oxides that were formed from diisopropylphosphoramidic dibromide (3) and an acetylenic Grignard reagent. The fourand six-edged macrocycles 15 and 16, in which the iPr2NP(O) units are connected through 1,3-butadiyne rods, were obtained from the monosilylated derivative of iPr2NP(O)(C2H)2 (7) by
具有炔属支架的磷基大环化合物是由乙炔取代的氧化膦构建的,该氧化膦由二异丙基二溴化磷 (3) 和炔属格氏试剂形成。iPr2NP(O)单元通过1,3-丁二炔棒连接的四边和六边大环15和16是从iPr2NP(O)(C2H)2(7)的单硅烷化衍生物通过多重乙炔偶联获得的氧化反应
