Abstract

In attempts to find appropriated methods for preparation of unstable sulfinyl and sulfonylphosphane complexes we have synthesized the diphenylphosphine complexes of Mn(I), BrMn(CO)4PHPh2, (1) and BrMn(CO)3(PHPh2)2 (2). Both should undergo electrophilic substitution in the presence of an adequated base. Parallel to the reactions of stabilization of phosphanes we have studied by means of x-ray analysis the structure of fac-BrMn(CO)3(PHPh2)2 (2). The compound crystallizes in the triclinic space group Pī, a = 9.840(2), b = 11.207(2), c = 13.083(3) Å, α = 72.00(3), β = 69.59(3), γ = 81.41(3)°, U = 1284.7(4) Å3, and Z = 2. In this complex the manganese atom shows an octahedral coordination geometry, with three carbonyl ligands in a fac arrangement, and one bromide and two diphenylphosphine ligands cis to each other.
