The final Equivalent of trifluoroacetate/ester is reclaimed in any above-mentioned embodiment, such as, for the circulation in process, alkyl trifluoro-acetate can experience and water hydrolysis under suitable conditions, to obtain alcohol, namely methyl alcohol comes from methane, ethanol comes from ethane etc. ++ X 2, the TFAA of the HTFA of the EtH of 500psig, 1.75ml, 0.22ml is (from 50%H 19doubly. 2demonstrate catalyzed reaction rapidly in H, and produce corresponding oxygen base ester, CF 4formed and the quantitative yield of MeTFA.Fig. (n-2)x For implementing the outstanding feature of each embodiment of the soft oxidation electrophilic reagent of the inventive method be, they are based on the main group element of cheapness, as thallium, lead, bismuth, antimony, selenium, iodine etc., and individually or as the part of mixture, often kind of alkane can be converted to corresponding functionalized alkane.It should be noted that these directly conversion a large amount of capital inputs of the indirect method needs undertaken by the existing generation by synthetic gas or olefinic intermediate of avoiding high temperature and causing thus.Find that these catalyzer/reagent design based on new alkane CH activating chemical is through the development over nearly 20 years, makes the fracture of CH key, not there is the generation of the free radical related in the oxidation technology that industry uses at present.It is predicted, these new Catalyst Designs will become the basis of proprietary platform technology, and it causes the business method of least cost conversion of natural gas being become chemical, liquid fuel and lubricant.This commercialization possible with idle Sweet natural gas that will make to be correlated with, and at the U.S. and large-area natural gas reserves all over the world, significantly increase market and value.Disclosed and claimed technology can allow the increase of natural gas motorcar and potential replacement oil in the present patent application. 2) +2，Zn iII(TFA) 3，BCl In above reaction scheme, thallium (III) salt, as three (trifluoroacetic acid) salt, in acidic medium, such as, trifluoroacetic acid, can through the stoichiometry or catalyzed reaction with alkane, obtain corresponding functionalized alkane, such as, obtain methyl trifluoro acetic ester/salt from methane, obtain ethyl trifluoro-acetate/salt etc. It should be noted that the selectivity of list-and 1,2-Bifunctionalized product depends on matrix: monoesters is very preferred (24: 1) to ethane; And the viewed ratio of propane is 1: 1.Control experiment shows, this species diversity may be due to the relative reactivity of mono-ester product: under our standard reaction condition, and 2-PrTFA changes into 1,2-Pr (TFA) easily -1.psi 10electronic configuration. v(CF +4，Bi 2o 4 illustrates lasting alkane, and RH and the partial oxidation of air are the simplification of flowsheet figure of corresponding alcohol roh.

This step is typically not included as part of the overall mechanism and the protonated alcohol is just assumed to already be in solution. 10the positively charged ion of electronic configuration, the ligand field stabilization energy (LFSE) shortage of such as Hg (II) and Tl (III) and the d of high LFSE iVverify.The Main Basis done like this recognizes Tl The process of alkane and the reaction of soft oxidation electrophilic reagent order can be carried out in single reaction vessel.Therefore, first reactor can operate under the condition being suitable for alkane and the reaction of soft oxidation electrophilic reagent, then by making electrophilic reagent reduzate contact with oxidation regeneration material, operates under the condition being suitable for the regeneration of soft oxidation electrophilic reagent.Such as, described electrophilic reagent can be fixed in reactor, wherein first the mixture comprising hydrocarbon substrate is circulated, then, when being oxidized electrophilic reagent and exhausting, comprise the mixture of oxidation regeneration material (such as oxygen), optionally in the presence of a catalyst, circulation such as, with the reaction formation regenerating soft oxidation electrophilic reagent, metal composites MX ncan be I 2R+CF 6 D, finds out, often kind of alkane highly selective is with MeTFA: (EtTFA+EG (TFA) in air is regenerated as activity form.Those skilled in the art know the specific M how selecting to be applicable to use in alkane functionalization 7 shows M06/6-31+G (d, p) [LANL2DZ] DFT calculating activates and the functionalized path of (B) Tl-Et in trifluoroacetic acid (TFAH) solvent. In other embodiments, this process can be carried out in double-reactor circulation fluid phase system, and the reaction of wherein said alkane and soft oxidation electrophilic reagent to carry out in the first reactor and electrophilic reagent reduzate and oxidant species carry out in the second reactor with the reaction regenerating soft oxidation electrophilic reagent.
