Reed, Thomas E. published the artcileComplexes of 1,6-naphthyridines. VI. Mixed ligand complexes of molybdenum hexacarbonyl, Application of 2,7-Dimethyl-1,8-naphthyridine, the publication is Inorganica Chimica Acta (1970), 4(3), 471-4, database is CAplus.
Mo(CO)3(N-N)L and Mo(CO)2(N-N)L2, where N-N is 2,7-dimethyl-1,8-naphthyridine (2,7-dmnapy), or 2,9-dimethyl-1,10-phenanthroline (2,9-dmphen) and L is a monodentate Lewis base (e.g., pyridines, MeCN, DMF, P(OR)3, PR3, AsPh3, SbPh3) were prepared and characterized by ir and PMR spectroscopy. The positions observed for the CO stretching modes of these complexes as well as the separation of the A’2 and A” modes of the tricarbonyl compounds suggests that the Ï-accepting ability of 2,7-dmnapy may be slightly greater than 2,2′-bipyridine (bipy), 1,10-phenanthroline (phen), or 2,9-dmphen. The ease of displacement N-N by Lewis bases depends on the concentrations and steric nature of the P donor and follows the order 2,7-dmnapy > bipy > phen â?2,9-dmphen. The unexpected shielding of N-N and L protons in the PMR spectra is discussed in terms of anisotropy produced by the aromatic systems.
