This communication describes a novel ruthenium-mediated transformation, which converts molecules containing alkenes and conjugated diynes such as 1-allyl-2-[6-(2-allylphenoxy)-2,4-hexadiynyl]oxy}benzene into dienynes such as 3-[2-(2,5-dihydro-1-benzoxepin-3-yl)-1-methylene-2-propenyl]-2,5-dihydro-1-benzoxepine instead of the expected product 3-[2-(2,5-dihydro-1-benzoxepin-3-yl)ethynyl]-2,5-dihydro-1-benzoxepine
该交流描述了一种新型的
钌介导的转化,该转化将含有烯烃和共轭二炔的分子(例如1-烯丙基-2-[[6-(2-烯丙基苯氧基)-
2,4-己二炔基]氧基}苯)转化为二烯(例如3) -[2-(2,5-二氢-1-苯并氧杂-3-基)-1-亚甲基-2-
丙烯基] -2,5-二氢-1-苯并
二氢吡啶代替预期产物3- [2-(2 ,5-二氢-1-苯并氧杂-3-基)
乙炔基] -2,5-二氢-1-苯并氧杂松。
