SDS of cas: 2398-37-0This research focused ontosyl alkdienylamine aryl bromide palladium catalyst Heck photochem arylation; arylvinyl tolylsulfonyl pyrrolidine preparation; aryl vinyl tolylsulfonyl piperidine preparation. The article conveys some information:
An unprecedented visible light enhanced room temperature Heck reaction between aryl halides and allenyl tosyl amines was here reported. A simple catalytic system (Pd(OAc)2/PPh3) was employed to afford arylated vinyl pyrrolidines and piperidines. A broad scope with high tolerance towards functional groups was observed Electronic effects play an important role in the efficiency of this process. Mechanistic studies, both exptl. and computational, indicated no evidence for a radical mechanism and a pivotal role of light in promoting the carbo-palladation step. The results came from multiple reactions, including the reaction of 1-Bromo-3-methoxybenzene(cas: 2398-37-0SDS of cas: 2398-37-0)
1-Bromo-3-methoxybenzene(cas: 2398-37-0) can be used in chemical reaction as intermediates to obtain target materials such as dyes, pharmaceuticals, perfumes, photoinitiators and agrochemicals.SDS of cas: 2398-37-0
