Chemistry is traditionally divided into organic and inorganic chemistry. Quality Control of 5-Bromobenzothiophene, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent£¬Which mentioned a new discovery about 4923-87-9
Copper-Catalyzed C2 and C3 Phosphonation of Benzofuran and Benzothiophene with Trialkyl Phosphites
A strategy for the selective phosphonation of benzofuran and benzothiophene with trialkyl phosphites was developed. In these reactions, the C?H phosphonation of benzofurans or benzothiophenes at the C2 or C3 position with trialkyl phosphites was successfully achieved without directing groups by using a copper catalyst. Additionally, the C5 phosphonation of furan was successful under the same conditions.
