Catalytic osmylation of cis and trans 2-cyclohexene-cyclohexanol (1a) and (1b) are carried out in the presence of N-methyl morpholine-N-oxide. Under the same conditions, only the cis isomer reacted, leading to triol (3). The steric hindrance of the equatorial OH group probably prevents the trans isomer from entering into such reaction. Triol (3) was also obtained from the reduction of the d...

epoxyalcohols are useful intermediates in complex organic synthesis, and recently they have been recognized as versatile intermediates for synthesis of natural products. the treatments of cis and trans 2-(1-cyclohexenyl) cyclohexanol, separately with paranirto perbenzoic acid gave the corresponding 2-(1- cyclohexenyl) cyclohexanol oxide. on the other hand, 2-cyclohexylidene cyclohexanol oxide w...

Diels-Alder reactions of substituted dienes and dienophiles have been found to cccur by both concerted and stepwise mechanisms.’.* The nature of the mechanism of the prototype Diels-Alder reaction of butadiene with ethylene to form cyclohexene is not only of fundamental interest but has generated fervid fulminations for favorite We wish to report new experimental evidence that is compatible onl...

Oxo- and imido-vanadium(V) metal complexes supported by bis(phenolate)-functionalized N-heterocyclic carbene (NHC) ligands were synthesized structurally identified. In the presence of [(Ph3P)2N]Cl ([PPN]Cl), saturated NHC oxo-vanadium showed activity in coupling CO2 cyclohexene oxide (CHO) into cis-cyclohexene carbonate (cis-CHC). More importantly, complex bearing less electron-donating benzann...

Cyclohexanol is an organic chemical intermediate product widely used in chemical<br /> industry and commonly produced by cyclohexene hydration. Because of the low mutual<br solubility water, reaction limited equilibrium,<br which has disadvantage conversion cyclohexene. In this paper, hydration catalysed A-36 cation exchange resin catalyst was analysed Aspen Plus V8.6 simulation sof...

Iron complexes including polyimidazole and exchangeable ligands are studied with the aim of modeling the structural and functional features of the non-heme iron centers of dinuclear proteins, such as methane monooxygenase. In [Fe(2)OL(2)(MeOH)(2)(NO(3))(2)](NO(3))(2) (1) (L = 2,6-bis(N-methylbenzimidazol-2-yl)pyridine), each Fe(III) is in a distorted octahedral environment and has a donor set o...
