Rhodium(III)‐Catalyzed Amidation of Unactivated C(sp3) H

Nitrogenation by direct functionalization of C H bonds represents an important strategy for constructing C N bonds. Rhodium(III)‐catalyzed direct amidation of unactivated C(sp 3) H bonds is rare, especially under mild reaction conditions. Herein, a broad scope of C(sp 3) H bonds are amidated under rhodium catalysis in high efficiency using 3‐substituted 1,4,2‐dioxazol‐5‐ones as the

N- versus O-Arylation of Aminoalcohols: Orthogonal

Two complementary protocols for copper-catalyzed arylation of aminoalcohols were developed. Selective N-arylation was accomplished at room temperature using 2-isobutyrylcyclohexanone (a β-diketone) as supporting ligand, while selective O-arylation required the use of 3,4,7,8-tetramethylphenanthroline at 80−110 °C. Systematic examination of the reaction scope revealed that high levels of

Suppressing Heavy Metal Leaching through Ball Milling of

Ball milling is investigated as a method of reducing the leaching concentration (often termed stablilization) of heavy metals in municipal solid waste incineration (MSWI) fly ash. Three heavy metals (Cu, Cr, Pb) loose much of their solubility in leachate by treating fly ash in a planetary ball mill, in which collisions between balls and fly ash drive various physical processes, as well as
