The very reactive bromo- and chloroacetylorganylphenylphosphanes X1X2X3CC(O)PRPh (1ax-dx, 1ay, by) are stabilized with BrMn(CO)5 (2) with formation of the complexes Br(OC)4Mn1X2X3> (3ax-dx, 3ay, by) and characterized in this way by their mass, IR and NMR spectra.According to an X-ray structural analysis 3dx crystallizes in the monoclinic space group P21/n with Z = 4.In the IR spectra of 3ax-cx and 3ay, by appear more than the expected four CO absorptions indicating the presence of rotamers.Reductive cyclization of Br(OC)4Mn (3by) with activated magnesium results in the formation of the cyclobutanone derivative (4).
