Abstract Ligand and CO binding constants are reported for Fe(C 4 -Cap) [1]. The results show that the CO affinities are Fe(C 2 -Cap)(B) ⋍Fe(C 3 -Cap)(B) > Fe(C 4 -Cap)(B). Also the CO affinities are Fe(Cap)(1,5-DCIm) > Fe(Cap) (1,2-Me 2 Im). These results are explained in terms of the possible steric factors involved.
摘要报道了Fe(C 4 -Cap)的
配体和CO结合常数[1]。结果表明,CO亲和力为Fe(C 2 -Cap)(B)⋍Fe(C 3 -Cap)(B)> Fe(C 4 -Cap)(B)。另外,CO亲和力为Fe(Cap)(1,5-
DCIm)> Fe(Cap)(1,2-Me 2 Im)。这些结果是根据可能涉及的空间因素进行解释的。
