Iridium-Catalyzed Direct Arene C–H Bond Amidation with Sulfonyl- and Aryl Azides
Iridium-catalyzed direct ortho C–H
amidation of arenes has
been shown to work well with sulfonyl- and aryl azides as the nitrogen
source. The reaction proceeds efficiently with a broad range of substrates
bearing conventional directing groups with excellent functional group
compatibility under mild conditions. In addition, substrates forming
not only 5- but also 6-membered iridacycle intermediates undergo the
C–H amidation with high selectivity

Borane-Catalyzed Selective Hydrosilylation of Internal Ynamides Leading to β‑Silyl (<i>Z</i>)‑Enamides
We
have developed a borane-catalyzed regio- and stereoselective
hydrosilylation of internal ynamides for the first time. The scope
of ynamide substrates and silane reactants was broad under mild reaction
conditions, affording synthetically versatile β-silyl (<i>Z</i>)-enamide products. The observed stereoselectivity was
reasoned to be due to the β-silicon effect on a postulated ketene
iminium intermediate
