We herein developed a mild and ligand‐free palladium‐catalyzed Heck–Matsuda reaction between Morita–Baylis–Hillman alcohols (MBHAs) aryl triazenes. After thorough screening of the acids, nitric acid (HNO3) was unexpectedly found to be most effective promoter for in situ generation arenediazonium salts. This coupling allows highly selective production various α‐arylmethyl β‐keto esters from readily accessible starting materials.
A copper-catalyzed novel synthesis of symmetric diarylamines was achieved from aryl boronic acids and NaNO2. This protocol employs as the commercially available arylation reagents sodium nitrite (NaNO2) cheap, stable, solid amino source. Under a simple ligand- base-free copper catalytic system (CuCl sole catalyst), wide range could be obtained in moderate to good yields. Notably, use Na15NO2 produce 15N-labeled diarylamines, which would otherwise difficult prepare by known methods.
An investigation into in-cylinder swirl and tumble flow characteristics with reduced maximum valve lifts (MVL) is presented. The experimental work was conducted in the modified four-valve optical spark-ignition (SI) test engine three different MVL. Particle image velocimetry (PIV) employed for measuring air motion measurement results were analyzed examining field, ratio variation fluctuating kinetic energy distribution. Results of ensemble-averaged fields show that MVL could produce strong...
