Metal derivatives of hexafluoroisopropyl alcohol and related compounds

Synthesis and reactivity of metal .alpha.-hydroxyalkyl complexes; generation of (CO)5MCH(C6H5)OH (M = Mn, Re)

“…These products will be interpreted (Discussion Section) as arising from -hydroxyalkyl complex 8. An independent generation of -hydroxyalkyl complex 8 from hydroxyacyl complex 5 was attempted (Scheme II). Treatment of 5 with (CH3)3N+-0~u nder conditions that successfully decarbonylated (silyloxy)acyl complex 4 (27) (a) Shvo, Y.; Hazum, E. J. Chem. Soc., Chem.…”

“…(B) A 5-mm septum-capped NMR tube was charged with 6 (0.058 g, 0.145 mmol). THF-<f8 (0.5 mL), and 1, 2,4,5-tetrachlorobenzene internal standard. The sample was cooled at -10 °C in a NMR probe.…”

Syntheses and reactions of a cationic hydrido(hydroxymethyl)iridium complex. The crystal and molecular structure of hydrido(hydroxymethyl)tetrakis(trimethylphosphine)iridium(III) hexafluorophosphate, [IrH(CH2OH) (PMe3)4][PF6]

“…69-112, 169 (1) C(H,2)-P(1)-C (12,3) 99.9-100.8 ( 3 the methyl complex 9 in good yield, free of other products (see Experimental Section). Likewise, the reaction of compound 13 with acid gives the methyl compound 14 with no observable byproducts.…”

Reduction of coordinated carbon monoxide. Synthesis of neutral metal formyl and hydroxymethyl derivatives of the (cyclopentadienyl)dicarbonyl(nitrosyl)rhenium(1+) cation

“…The only other -hydroxyalkyl metal compound reported was (C5H5)Fe(CO)2[C(CF3)2OH], which was synthesized by Stone from (CsH5)Fe(CO)2-and hexafluoroacetone. 25 Gladysz has attempted generation of (CO)sMnCH(OH)C6H5 by two different routes but found that the presumed intermediate was not observable even at -50 °C and only benzaldehyde and HMn(CO)s could be detected. 17 Pruett proposed hydroxymethyl-and 1,2-dihydroxyethylrhodium intermediates in the rhodium cluster catalyzed conversion of CO/H2 mixtures into ethylene glycol.26 Feder has suggested hydroxymethylcobalt species as precursors of methanol in the cobalt carbonyl catalyzed reduction of CO by H2.…”
