icobalt) complexes. The structure of one of them, [PhNC(CCPh)2]Co2(CO)6 (4b), has been determined by X-ray crystallography, which shows that the phenyl ring on the imino nitrogen is oriented over the free acetylenic bond. The N-phenyl dialkynyl imine-mono(hexacarbonyldicobalt) complex thus formed undergoes cotrimerization with disubstituted alkynes to give pentasubstituted aryl alkynyl N-phenyl imines
N-苯基二炔基亚胺与八羰基二钴反应,得到N-苯基二炔基亚胺-单(六羰基二钴)配合物。其中之一[PhN determinedC(CCPh)2 ] Co 2(CO)6(4b)的结构已通过X射线晶体学测定,结果表明亚氨基氮上的苯环取向于游离炔键。的Ñ -苯基dialkynyl亚胺-单(hexacarbonyldicobalt)络合物如此形成经历cotrimerization与二取代的炔烃,得到五取代的芳基炔基ñ -苯基亚胺。N-苯基烯基炔基亚胺,通过N的1,2-还原制得-苯基二炔基亚胺随后异构化,也通过相应的N-苯基炔基亚胺-六羰基二钴配合物转化为五取代的芳基烯基N-苯基亚胺。
