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 Isodesmic C-H Borylation: Perspectives and Proof of Concept of Transfer Borylation Catalysis, published in 2019-08-07, which mentions a compound: 16400-32-1, mainly applied to heteroarene borylation pyrrole indole arylboronate mercaptopyridine catalyst; borylated alkynylindole preparation crystal structure; mol structure borylated alkynylindole; pyrrole borylated preparation, Product Details of 16400-32-1.
The potential advantages of using arylboronic esters as B source in the C-H borylation are discussed. The concept is showcased by using com. available 2-mercaptopyridine as a metal-free catalyst for the transfer borylation of heteroarenes, using arylboronates as borylation agents. The catalysis shows a unique functional group tolerance among C-H borylation reactions, tolerating notably terminal alkene and alkyne functional groups. The computational study of the mechanism is also described.
From this literature《Isodesmic C-H Borylation: Perspectives and Proof of Concept of Transfer Borylation Catalysis》,we know some information about this compound(16400-32-1)Product Details of 16400-32-1, but this is not all information, there are many literatures related to this compound(16400-32-1).
