Mn(η-C_4H_4N)(CO)_3与弱碱类配位体P(OEt)_3和P(ph)_3反应产生单取代衍生物,而它与强碱类配位体P(C-HX)_3和P(n-Bu)_3反应产生单和二取代衍生物.反应为二级取代过程,一级为Mn(η-C_4H_4N)(CO)_3一级为配位体.此外,反应速率决定于配位体的性质,特别是它的碱性和大小,活化参数进一步支持在萘烷中反应为缔合性质SN_2. The reaction of Mn (η-C_4H_4N) (CO) _3 with the weakly basic ligands P (OEt) _3 and P (ph) _3 yields monosubstituted derivatives which interact with the strong base ligand P (C-HX) 3 and P (n-Bu) 3 to produce mono- and di-substituted derivatives.The reaction is secondary substitution process, the first order is Mn (η-C_4H_4N) (CO) _3 first order ligand.In addition, the reaction rate determines The nature of the ligand, especially its basicity and size, further supports the activation parameter in decalin to an associative property SN_2.
