  Cationic carbonylmanganese complexes of the olefinic ligand tri(1-cyclohepta-2,4,6-trienyl)phosphane, P(C7H7)3

  摘要：

  A series of tetrafluoroborate salts of carbonylmanganese cations was obtained which contain the olefinic phosphane, P(C7H7)3 (1). Whereas 1 is a conventional two-electron phosphatic ligand ([P]) in {Mn(CO)(5)[P]}BF4 (2)-as in the neutral bromide or trifluoroacetate complexes, cis-{Mn(X)(CO)(4)[P]}BF4 (X = Br (4b), CF3COO (4d)) and mer, trans-{Mn(X)(CO)(3)[P]}BF4 (X = Br (5b), CF3COO (5d))-it is transformed into a four-electron chelate ligand ([P']) if 4b and 5b react with AgBF4 to give cis-{Mn(CO)(4)[P']}BF4 (7) and mer, trans- {Mn(CO)(3)[P][P']}BF4 (8), respectively, ([P'] = P(C7H7)(2)(eta(2)-C7H7)). An analogous halide abstraction by AgBF4 converts mer-{Mn(I)(CO)(3)[P']} (6c) into fac-{Mn(CO)(3)[P"]}BF4 (9) which contains the phosphane as a six-electron ligand ([P"]) with an eta(4)-norcaradienyl ring ([P"] = P(C7H7)(2)(eta(4)-C7H7)). The coordinated eta(2)-cyclohepta-2,4,6-trienyl substituent in 7 and 8 is displaced by tert-butyl isocyanide (L) to give cis-{Mn(CO)(4)[P](L)}BF4 (10) and mer,trans-{Mn(CO)(3)[P](2)(L)}BF4 (11), respectively. The structures of the new cations have been assigned on the basis of their carbonyl stretching absorption patterns in the IR spectra and by their H-1-, C-13- and P-31-NMR spectra. Single-crystal X-ray structure analyses were carried out for 7 and 9. (C) 2003 Elsevier B.V. All rights reserved.
