Experimental and computational studies on H<sub>2</sub>O-promoted, Rh-catalyzed transient-ligand-free <i>ortho</i>-C(sp<sup>2</sup>)–H amidation of benzaldehydes with dioxazolones
We develop an efficient and convenient ligand-free, rhodium-catalyzed ortho-C(sp2)–H amidation of benzaldehydes with dioxazolones using H2O as the key promoter.

A facile alkenylation of quinazolines with unactivated terminal alkynes has been achieved in the presence of KOtBu without the aid of any transition metal catalysts. The reaction is carried out under very mild conditions and shows a high stereoselectivity. A possible radical-based mechanism is also explored.
