《meta-Selective C-H functionalisation of aryl boronic acids directed by a MIDA-derived boronate ester》 was written by Williams, Alexander F.; White, Andrew J. P.; Spivey, Alan C.; Cordier, Christopher J.. Formula: C7H9BO3 And the article was included in Chemical Science in 2020. The article conveys some information:
N-Methyliminodiacetic acid (MIDA) boronates are boronic acid derivatives which are stable to reduction, oxidation and transmetalation. This has led to their widespread use as boronic acid protecting groups (PGs) and in iterative cross-couplings. authors describe herein the development of a novel MIDA derivative that acts in a dual manner, as a protecting group and a directing group (DG) for meta C(sp2)-H functionalisation of arylboronic acids. Palladium catalyzed C-H alkenylations, acetoxylations and arylations are possible, at room temperature and under aerobic conditions. Deprotection to reveal the functionalized boronic acids is rapid and allows for full recovery of the DG. The technique allows the facile diversification of aryl boronic acids and their subsequent use in a range of reactions or in iterative processes. After reading the article, we found that the author used 3-Methoxyphenylboronic acid(cas: 10365-98-7Formula: C7H9BO3)
3-Methoxyphenylboronic acid(cas: 10365-98-7) belongs to boronic acids. Boronic acids are mild Lewis acids which are generally stable and easy to handle, making them important to organic synthesis.Formula: C7H9BO3
