Selective CH functionalization of methane, ethane, and propane by a perfluoroarene iodine(III) complex.
نویسندگان
چکیده
Direct partial oxidation of methane, ethane, and propane to their respective trifluoroacetate esters is achieved by a homogeneous hypervalent iodine(III) complex in non-superacidic (trifluoroacetic acid) solvent. The reaction is highly selective for ester formation (>99%). In the case of ethane, greater than 0.5 M EtTFA can be achieved. Preliminary kinetic analysis and density functional calculations support a nonradical electrophilic CH activation and iodine alkyl functionalization mechanism.

Partial oxidation of light alkanes by periodate and chloride salts.
The efficient and selective partial oxidation of light alkanes using potassium periodate and potassium chloride is reported. Yields of methane functionalization in trifluoroacetic acid reach >40% with high selectivity for methyl trifluoroacetate. Periodate and chloride also functionalize ethane and propane in good yields (>20%).
متن کاملSolubility of Methane, Ethane, and Propane in Pure Water Using New Binary Interaction Parameters
Solubility of hydrocarbons in water is important due to ecological concerns and new restrictions on the existence of organic pollutants in water streams. Also, the creation of a thermodynamic model has required an advanced study of the phase equilibrium between water (as a basis for the widest spread muds and amines) and gas hydrocarbon phases in wide temperature and pressure ranges. Therefore,...
متن کاملSilica-supported tantalum clusters: catalyst for alkane conversion.
Silica-supported tantalum clusters (on average, approximately tritantalum) were formed by the treatment, in either H(2) or ethane, of adsorbed Ta(CH(2)Ph)(5); the supported catalyst is active for ethane conversion to methane and propane at 523 K, with the used catalyst containing clusters of the same average nuclearity as the precursor.
متن کاملLaser-induced fluorescence monitoring of higher alkanes production from pure methane using non-oxidative processes.
A novel method for the study of non-oxidative methane conversion process into higher value hydrocarbon and hydrogen has been invented. The method involves the multiphoton dissociation of methane under the influence of the high power pulsed ultraviolet laser radiation at 355 nm wavelength at room temperature (293 K) and standard pressure (1 atm). The products generated as a result of methane con...
