Reaction of chromyl chloride with donor molecules

Abstract

Reaction of chromyl chloride with various donor molecules led to solid products of compositions CrO2Cl2.2D (D = acetone or dimethylsulfoxide), 2CrO2Cl2.3D (D = tetrahydrofuran, 1,4-dioxan, or 4-picoline), CrO2Cl2.D (D = diethyl ether, triphenylphosphine, or triphenylarsine), and 2CrO2Cl2.(C6H5)3N. Acetonitrile failed to react. Infrared and ultraviolet spectra, X-ray diffraction and magnetic measurements, and the organic products obtained on hydrolysis were interpreted as showing that none of these complexes are Lewis adducts of chromyl chloride, but that all contain chromium(IV).

“…), [CrO 2 Cl 2 (py) n ] (n = 1 or 2), chromium(V) complexes [CrOCl 3 Cl]. [12][13][14][15][16][17][18][19][20] There are major disagreements between the reports about the identity, purity and the spectroscopic properties of the products. X-ray structural authentications are completely lacking.…”

Cobalt(II) Mercury Tetrathiocyanate Complexes with Lewis Bases

“…The dioxane and tetrahydrofuran complexes show features typical of the coordinated molecules in the range 1250-800 cm-'. In particular the absorption bands associated with the C-0-C antisymmetric stretch show the expected frequency decreased in each case (12)(13)(14), i.e., the strong 1070 cm-' band in tetrahydrofuran moves to 1035 (m) cm-I, the strong 1120 cm-' band of dioxane appears at 1045 (ms) cm-', the tetrahydrofuran band at 908 cm-' moves to 877 cm-' and the dioxane band at 887 to 860cm-', respectively. The dioxane compound also shows a b s o r p t i o n b a n d…”

Intermediates and activated complexes in the chromyl chloride oxidation of organic compounds

“…octalin (26,27) If the postulate that cycloalkenes are intermediates in the chromyl chloride oxidation of cycloalkanes is valid, then it is reasonable to expect the oxidation of cycloalkenes to lead to the same products. This has been shown to be the case with 15, 1-methylcyclopentene, methylenecyclopentene, 9, 22, and 23 (Table II) a°' 41 .…”
