Aryl carbamates were for the first time applied as electrophiles in the cross‐coupling with arylsilanes via nickel or iron catalysis to construct valuable biaryl compounds. This new coupling reaction features a good group tolerance and non‐sensitivity to steric hindrance on both aryl carbamates and arylsilanes.

zed dominoreaction was developed to yield functionalizednaphthalenes, quinolines, and isoquinolines. The reactions of various substituted 1-phenylprop-2-yn-1-ols containing electron-donating (EDG) and electron-withdrawing (EWG) groups and 1-heteroarylprop-2-yn-1-ols worked well with this procedure. Both electron-rich and -deficient aryl halides were satisfactory substrates for this reaction. This
