Method and system for hybrid catalytic biorefining of biomass to methylated furans and depolymerized technical lignin

A method is disclosed for converting biomass into a fuel additive, the method comprising: liquefying the biomass to form a liquor; neutralizing the liquor; precipitating lignin out of the liquor; extracting furfural (FF) and 5-hydroxymethylfurfural (HMF) from the liquor; and hydrodeoxygenating (HDO) the extracted furfurals over a Cu—Ni/TiO.sub.2 catalyst. The catalyst for hydrodeoxygenating (HDO) furfural (FF) and 5-hydroxymethylfurfural (HMF) to methylated furans comprises copper-nickel (Cu—Ni) particles supported on titanium dioxide (TiO.sub.2), and wherein the copper-nickel particles form core-shell structures in which copper (Cu) is enriched at a surface of the catalyst.

Slow release of organoboronic acids in cross-coupling reactions

A method of performing a chemical reaction includes reacting a compound selected from the group consisting of an organohalide and an organo-pseudohalide, and a protected organoboronic acid represented by formula (I) in a reaction mixture:
R.sup.1—B-T  (I);
where R.sup.1 represents an organic group, T represents a conformationally rigid protecting group, and B represents boron having sp.sup.3 hybridization. When unprotected, the corresponding organoboronic acid is unstable by the boronic acid neat stability test. The reaction mixture further includes a base having a pK.sub.B of at least 1 and a palladium catalyst. The method further includes forming a cross-coupled product in the reaction mixture.
