In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Regioselective oxidative Pd-catalysed coupling of alkylboronic acids with pyridin-2-yl-substituted heterocycles, published in 2015, which mentions a compound: 123784-07-6, mainly applied to regioselective oxidative coupling alkylboronic acid pyridinyl heterocycle palladium catalyst, HPLC of Formula: 123784-07-6.
A total of 19 alkylated heterocycles (thiophenes, benzothiophenes, pyrroles, furans) were prepared (36-99% yield) from the resp. pyridin-2-yl-substituted precursors employing alkylboronic acids as the C-H alkylating reagents in an oxidative (Ag2CO3 and 2,6-dimethyl-1,4-benzoquinone as oxidants) Pd-catalyzed coupling reaction. E.g., in presence of Pd(OAc)2 and Ag2CO3 and 2,6-dimethyl-1,4-benzoquinone as oxidants, regioselective alkylation of 2-pyridin-2-ylthiophene with BuB(OH)2 gave 71% I.
There are many compounds similar to this compound(123784-07-6)HPLC of Formula: 123784-07-6. if you want to know more, you can check out my other articles. I hope it will help you，maybe you’ll find some useful information.
