  • Patent number: 10745340
    Abstract: The invention provides processes and materials for the efficient and cost-effective functionalization of alkanes, such as methane from natural gas, to provide esters, alcohols, and other compounds. The method can be used to produce liquid fuels such as methanol from a natural gas methane-containing feedstock. The soft oxidizing electrophile, a compound of a main group, post-transitional element such as Tl, Pb, Bi, and I, that reacts to activate the alkane C—H bond can be regenerated using inexpensive regenerants such as hydrogen peroxide, oxygen, halogens, nitric acid, etc. Main group compounds useful for carrying out this reaction includes haloacetate salts of metals having a pair of available oxidation states, such as Tl, Pb, Bi, and I.

  • Patent number: 10011547
    Abstract: Provided are methods and materials for the functionalization of a heteroalkane or arene using an oxidizing electrophile as a stoichiometric agent or catalyst. The reaction involves the replacement of a hydrogen atom on an sp3-hybridized carbon atom of the heteroalkane or of a hydrogen atom on an sp2-hybridized carbon atom of the arene. A main group element organometallic intermediate is formed that undergoes further conversion to a functionalized heteroalkane or arene.
