- 中文摘要: Direct reaction of iron pentacarbonyl with 1-N,N- disubstituted-cyclohexa-2,5-dienecarboxamide and 1-N,N- disubstituted-cyclohexa-1,3-dienecarboxamide mixture (in which the disubstituted group is diethyl or diphenyl) gave the isomeric tricarbonyl iron complexes of 2-N,N- disubstituted-1,4-.eta.-cyclohexa-1,3-dienecarboxamide, (1), 1-N,N-disubstituted-1,4-.eta.-cyclohexa-1,3- dienecarboxamide, (2), and 5-N,N-disubstituted-1,4-.eta.- cyclohexa-1,3-dienecarboxamide, (3) and tricarbonyl iron complexes of 1-N,N-disubstituted-cyclohexenecarboxamide. These complexes were separated and characterized by IR, UV- VIS, /sup 1/H NMR, elemental analysis, and mass spectra. Only 1 isomerized to give 2 under acidic conditions; both 1 and 2 undergo hydride abstraction with triphenylmethyl hexafluorophosphate. Complexes 3, undergo neither isomerization nor hydride abstraction. According to the spectral data, the possible interaction between carboxamide and iron carbonyl moiety was investigated. The irreversible electrochemical behavior of these complexes were studied.
