Abstract
Manganese carbonyl complexes bearing dibenzophospholyl (DBP) and 1-phenyldibenzophosphole (Ph-DBP) ligands have been prepared. Reaction of Li-DBP with Mn(CO)5Br gave (µ2-DBP)(µ2-Br)Mn2(CO)8, while reaction of bis(1,1'-dibenzophospholyl) and Mn2(CO)10 yielded (µ2-DBP)2Mn2(CO)8. The phosphine adducts (Ph-DBP)Mn2(CO)9 and (Ph-DBP)2Mn2(CO)8 were obtained by reaction of Ph-DBP and Mn2(CO)10. The ligands are σ-bonded through the phosphorus atom in all complexes. The compounds were characterized by 1H, 13C, and 31P NMR and IR spectroscopy, mass spectrometry, and X-ray diffraction.Key words: dibenzophospholyl, dibenzophosphole, manganese, heterocycle.
