Pd-Catalyzed Cross-Coupling Reactions of Amides and Aryl Mesylates
摘要:
A catalyst, based on a biarylphosphine ligand, for the Pd-catalyzed cross-coupling reactions of amides and aryl mesylates is described. This system allows an array of aryl and heteroaryl mesylates to be transformed into the corresponding N-aryl amides in moderate to excellent yields.

An iron‐catalyzed oxidative coupling reaction of isocyanide and readily available alkane has been disclosed. In the presence of a catalytic amount of FeCp2 (10 mol%), heating a mixture of alkane, isocyanide, and DTBP in DCE allows for the formation of an amide. This reaction tolerates many simple alkanes including cycloalkanes and chain alkanes. Furthermore, a series of aromatic isocyanides having
chromium-catalyzed activation of acyl C–O bonds with magnesium for amidation of esters with nitroarenes. Low-cost chromium(III) chloride shows high reactivity in promoting amidation by using magnesium as reductant and chlorotrimethylsilane as additive. It provides a step-economic strategy to the synthesis of centrally important amide motifs using inexpensive and air-stable nitroarenes as amino sources.
