In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called From 1,2-difunctionalisation to cyanide-transfer cascades – Pd-catalysed cyanosulfenylation of internal (oligo)alkynes, published in 2020, which mentions a compound: 40400-13-3, Name is 1-(Bromomethyl)-2-iodobenzene, Molecular C7H6BrI, Quality Control of 1-(Bromomethyl)-2-iodobenzene.
Internal alkynes substituted by aliphatic or aromatic moieties or by heteroatoms were converted into sulfur-substituted acrylonitrile derivatives Key is the use of Pd catalysis, which allows the addition of aromatic and aliphatic thiocyanates in an intra- and intermol. manner. Substrates with several alkyne units underwent further carbopalladation steps after the initial thiopalladation step, thus generating in a cascade-like fashion an oligoene unit with sulfur at one terminus and the cyano group at the other.
From this literature《From 1,2-difunctionalisation to cyanide-transfer cascades – Pd-catalysed cyanosulfenylation of internal (oligo)alkynes》,we know some information about this compound(40400-13-3)Quality Control of 1-(Bromomethyl)-2-iodobenzene, but this is not all information, there are many literatures related to this compound(40400-13-3).
