Über π-Allyl-Komplexe des Molybdäns II. Die bildung von π-Allyldicarbonylmolybdän-Komplexen aus Molybdän-hexacarbonyl und seinen Derivaten

Syntheses, structures, and dynamic properties of M(CO)2(η3-C3H5)(en)(X) (M=Mo, W; X=Br, N3, CN) and [(en)(η3-C3H5)(CO)2M(μ-CN)M(CO)2(η3-C3H5)(en)]Br (M=Mo, W)

“…Reagents were used as obtained from the commercial suppliers, and solvents were dried and freshly distilled prior to use. Mo(CO) 2 (g 3 -C 3 H 5 )(CH 3 CN) 2 (Br) and W(CO) 2 (g 3 -C 3 H 5 )(CH 3 CN) 2 (Br) were prepared by the literature procedures [3]. Elemental analyses were recorded on a Hitachi 270-30 spectrometer.…”

“…The group 6 metal allyl complexes M(CO) 2 (g 3 -C 3 H 5 )(L-L)(X) (M = Mo, W; L-L = bidentate ligand; X = anionic monodentate ligand) have been studied for more than four decades [1][2][3] due to their conformational and dynamic behavior [4][5][6] as well as their possible application in organic synthesis [7][8][9][10][11][12]. In general, when L-L is a rigid bidentate ligand the complex adopts conformation A (Scheme 1) in the solid state and displays non-fluxional behavior in solution [13,14].…”

Syntheses, structures, and dynamic properties of M(CO)2(η3-C3H5)(L–L)(NCBH3) (M=Mo, W; L–L=dppe, bipy, en)

“…Unless otherwise noted, reagents were used as obtained from the commercial suppliers, and solvents were dried and freshly distilled prior to use. Mo(CO) 2 (g 3 -C 3 H 5 )-(CH 3 CN) 2 Br and W(CO) 2 (g 3 -C 3 H 5 )(CH 3 CN) 2 Br were prepared by the literature procedures [20]. Elemental analyses were recorded on a Hitachi 270-30 spectrometer.…”

Molybdenum Carbonyl Complexes Bearing PN Ligands Based on 2‐Aminopyridine

“…The solvents were purified according to standard procedures. [11] The ligands 2-(diphenylphosphanylamino)pyridine (PN-Ph), [4e,5] 2-amino-N-(diisopropylphosphanyl)pyridine (PN-iPr), [2] [2] and dimethyl (4S,5S)-2-[(2-pyridyl)amino]-1,3,2-dioxaphospholane-4,5-dicarboxylate (PN-TAR Me ) [2] and Mo(η 3 -CH 2 CHCH 2 )(CO) 2 (CH 3 CN) 2 -Br [12] were prepared according to the literature. The deuterated solvents were purchased from Aldrich and dried with 4-Å molecular www.eurjic.org4090 sieves.…”
