for site‐selectivefunctionalization of unactivated methylene and methine C−H bonds enabled by an FeII‐catalyzed redox process is described. The mild, expeditious, and modular protocol allows efficient remote aliphatic fluorination, chlorination, amination, and alkynylation of structurally and electronically varied primary, secondary, and tertiary hydroperoxides with excellent functional‐group tolerance

Studies of the bromine-silver carbonate reaction with aliphatic alcohols in which intramoleular δ-H competition is possible are generally quite specific. Loss of tertiary δ- hydrogen occurs preferentially from both tertiary and secondary alfphatic alcohols to yield the most highly substituted cyclic ether. For example, 2,5-dimethyl-2-octanol yields only 2,2,5-trimethyl-5-propyletrahydrofuran as the

In one aspect, this invention relates to production of useful fermentation end-products from biomass through simultaneous hydrolysis and fermentation by a microorganism, such as
Clostridium phytofermentans
. The invention also relates to the development of a process for efficient pretreatment and conversion of lignocellulosic biomass to end-products with high conversion efficiency (yield). In another aspect, methods for producing a fermentation end-product by fermenting hexose (C6) and pentose (C5) sugars with a microorganism, such as
Clostridium phytofermentans
are disclosed herein.
Methods, enzymes, recombinant microorganism, and microbial systems are provided for converting polysaccharides, such as those derived from biomass, into suitable monosaccharides or oligosaccharides, as well as for converting suitable monosaccharides or oligosaccharides into commodity chemicals, such as biofuels. Commodity chemicals produced by the methods described herein are also provided. Commodity chemical enriched, refinery-produced petroleum products are also provided, as well as methods for producing the same.
