“…Photolysis of hexacarbonylchromium(0) in the presence of 2,6-diaminopyridine in toluene solution at 10 °C yields pentacarbonyl(2,6-diaminopyridine)chromium(0), which could be isolated from solution as plate-like crystals (Scheme 34). The 2,6-diaminopyridine ligand is bonded to the chromium atom through one of the NH2 groups [157].…”

KEYWORDSThe special interest attached to the chemistry of metal carbonyls arises from several causes. While quite distinct from the metal carbonyls in the organometallic compounds, they differ in physical properties (e.g., their volatility) from all other compounds of the transition metals. Chemically, they constitute a group of compounds in which the formal valency of the metal atoms is zero, and in this respect (apart, perhaps, from the ammoniates of the alkali metals) they are comparable only with the recently discovered compounds. As a class, the carbonyls are reactive compounds, and a number of new types of inorganic compounds have been discovered. In the concepts for new products, performance, product safety, and product economy criteria are equally important. They are taken into account already when the raw material base for a new industrial product development is defined. Since the discovery of nickel carbonyl by Mond and Langer in 1888, the carbonyls of the iron group and of chromium, molybdenum and tungsten have found important technical applications, e.g., in the Mond nickel process, and for the preparation of the metals in a state of subdivision and of purity suitable for powder metallurgy, for catalysts, etc. The reaction mechanism of the processes developed for producing the carbonyls technically has only recently received its interpretations. Within the space of review it is necessary to limit discussion to a few topics. Particular stress has accordingly laid upon (a) the chemical bonding in metal carbonyls, (b) importance of IR and NMR spectroscopy in characterization of metal carbonyls, (c) substitution reactions of G-VIb metal carbonyls, (d) kinetics and mechanism of substitution reactions in metal carbonyls, (e) substituted complexes of G-VIb metal carbonyl, (f) chelate complexes of G-VIb metal carbonyls, (g) uses of G-VIb metal carbonyl complexes and (h) studies done on G-VIb metal carbonyls.

“…In an article in press as of this writing, Ö zkar and coworkers have described the synthesis and molecular structure of Cr(CO) 5 (2,5-diaminopyridine), Fig. 12 [114]. Tilset and coworkers have recast the King and Wojiciki acyl decarbonylation reactions in a new light with the photochemical synthesis of TpFe(CO)(PMe 3 )Me from TpFe(CO)(PMe 3 )(C(‚O)Me), Fig.…”

“…The photochemical reactions and other treatments of organometallic compounds such as purification and crystallization were followed by recording ir spectra from solutions on a Perkin-Elmer 16 PC FT-IR spectrophotometer. nmr spectra were recorded on a Bruker Avance DPX 400 (400.1 MHz for 1 H; and 100.6 MHz for 13 C spectrometer). TMS was used as internal reference for 1 H-and 13 C-nmr chemical shifts.…”

“…Therefore, pyridine derivatives having ligating atoms in the 2-or 6-position are expected to show more than one binding mode to the central atom. However, a recent study has shown that 2,6-diaminopyridine is bonded to the central atom through one sp 3 -hybridized nitrogen of the amino group [13]. The effect of substituent in position 4 on the bonding mode and stability of the M-N bond appeared to be of interest as the steric hindrance for coordination of pyridine is not operating at all.…”

Carbonyl-metal (M:Cr, Mo, W) derivatives of 4-substituted pyridines [4-methylpyridine (4-mp), 4-tert-butylpyridine (4-tbp) and 4-dimethylaminopyridine (4-dmap)] where the metal center is bonded to the nitrogen atom of the substituted pyridine ring are described. The organometallic complexes, M(CO) 5 L, were synthesized by either the direct reaction of the metal hexacarbonyls or by the thermal substitution of M(CO) 5 (THF) with the pyridine ligands; 4-methylpyridine (1), 4-tert-butylpyridine (2), 4-dimethylaminopyridine (3). The reported complexes were purified by column chromatography and recrystallization. The complexes were all characterized in solution by elemental analysis, MS, ir , 1 H-nmr and 13 C-nmr spectroscopies.
