The carbonylative cross coupling of aryl iodide with ortho-haloaniline to ortho-haloanilide using phosphine-free Pd(OAc)2 catalyst in water as a reaction medium has been studied. The present protocol facilitated the reaction of o-haloanilines with a wide variety of hindered and functionalized ...
The scope and limitations of the Pd(OAc)2/DABCO (1,4-diaza-bicyclo[2.2.2]octane)-catalyzed Suzuki–Miyaura cross-coupling reactions have been demonstrated. The results showed that the effect of solvent had a fundamental influence on the reaction. In the presence of Pd(OAc)2 and DABCO, bot...
Pd(OAc) 2 -catalyzed dehydrogenative C–H activation: An expedient synthesis of uracil-annulated β-carbolinones An intramolecular dehydrogenative C–H activation enabled an efficient synthesis of an uracil-annulated β-carbolinone ring system. The reaction is simple, efficient and high yielding (85...
