《Palladium-Catalyzed Direct C-H Arylation of Arenes Promoted by Quaternary Ammonium Salt》 was published in Asian Journal of Organic Chemistry in 2020. These research results belong to Yang, Sabyuk; Hong, Soon Hyeok. Computed Properties of C7H7BrO The article mentions the following:
A new Pd-based catalytic system for the direct C-H arylation of arenes was developed. The use of a substoichiometric amount of quaternary ammonium salt as an additive with a Pd source achieved the direct arylation of unactivated arenes under milder reaction conditions in moderate to high yields. The ammonium salt generated the anionic palladium complex, thereby facilitating arylation by a concerted metalation-deprotonation process. In the experiment, the researchers used 1-Bromo-3-methoxybenzene(cas: 2398-37-0Computed Properties of C7H7BrO)
