precious-metal catalysts for C-H bond cleavage and, as a result, display high selectivity for borylation of aromatic C(sp2)-H bonds over aliphatic C(sp3)-H bonds4. Here we report a mechanistically distinct, metal-free borylation using hydrogen atom transfer catalysis5, in which homolytic cleavage of C(sp3)-H bonds produces alkylradicals that are borylated by direct reaction with a diboron reagent. The reaction
Disclosed are electrolytes that are organosilicon phosphorus-based, and supercapacitors which incorporate them. These electrolytes are cationic salts with a phosphorous containing organosilicon moiety. They appear particularly suitable for use in applications such as electric and hybrid electric vehicles.

(LMCT) process. These reactions exhibit remarkably broad substrate scope (>150 examples in total), and most importantly, all of these three reactions show unconventional regioselectivity, with the occurrence of C(sp3)–H borylation, thiolation, and sulfinylation preferentially at the distal methyl position. The procedures are operationally simple and readily scalable and provide access to high-value products
