In this paper, we developed a rhodium-catalyzed annulation of vinylene carbonate with amidines, leading to 4-methylquinazolines with moderate to excellent yields. This procedure proceeded by sequentialortho-acylation and annulation, where vinylene carbonate served as the acetylation reagent rather than the ethyne surrogate.

This work reports a mild and efficient approach for the synthesis of substituted quinazolines using 1-(2-aminoaryl)ethan-1-ones in conjunction with arylmethanamines as starting materials via visible-light-induced benzylic C–H functionalization. The reaction proceeded at room temperature with low catalyst loading and the reaction system was clean from beginning to end. Significantly, this method exhibited good tolerance even to free hydroxyl group and amino group contained in substrates.

We report a facile method for assembly of a monolayer array of nitrogen-doped graphene (NG) and nanoparticles (NPs) and the subsequent transfer of two layers onto a solid substrate (S). Using 3 nm NiPd NPs as an example, we demonstrate that NiPd-NG-Si (Si=silicon wafer) can function as a catalyst and show maximum NiPd catalysis for the hydrolysis of ammonia borane (H3NBH3, AB) with a turnover frequency (TOF) of 4896.8 h?1 and an activation energy (Ea) of 18.8 kJ mol?1. The NiPd-NG-S catalyst is also highly active for catalyzing the transfer hydrogenation from AB to nitro compounds, leading to the green synthesis of quinazolines in water. Our assembly method can be extended to other graphene and NP catalyst materials, providing a new 2D NP catalyst platform for catalyzing multiple reactions in one pot with maximum efficiency.
