CAS:7-(4-Bromobutoxy)-3,4-dihydroquinolin-2-one is a palladium catalyst that can be used in a Buchwald reaction. This reaction is an industrially scalable process that has been developed to produce high yields of valuable organic compounds from inexpensive starting materials. The catalytic cycle involves the formation of the palladium species Pd(0) followed by its oxidative addition to an alkyl halide. This addition leads to the formation of a palladium(II) species and subsequent reductive elimination of hydrogen halide. 7-(4-Bromobutoxy)-3,4-dihydroquinolin-2-one is used as a catalyst in this process because it selectively reacts with electron rich aromatic substrates to form substituted benzoquinones or phenols. The product distribution is determined by the reactivity of the substrate and the relative rates of competing reactions.
