In 2019,Advanced Synthesis & Catalysis included an article by Zhang, Heng; Yu, Yinghua; Huang, Shenlin; Huang, Xueliang. Synthetic Route of C7H5BrO. The article was titled 《Palladium-Catalyzed Cascade Reaction of o-Bromobenzaldehydes with N-Sulfonylhydrazones: An Efficient Approach to the Naphthalene Skeleton》. The information in the text is summarized as follows:
A new strategy for the construction of the naphthalene backbone was described. The reaction essentially started from two simple aldehydes. The key step was enabled by a palladium-carbene migratory insertion. After that, a sequence of reversible allylic alkylation and intramol. condensation took place to give the substituted naphthalene derivatives Addnl. manipulations on the sulfonyl group in the product via palladium-catalyzed Kumada coupling were also investigated.o-Bromobenzaldehyde(cas: 6630-33-7Synthetic Route of C7H5BrO) was used in this study.
o-Bromobenzaldehyde(cas: 6630-33-7) is used in L-threonine aldolase-catalyzed enantio/diastereoselective aldol reactions.Synthetic Route of C7H5BrOSynthetic applications of o-Bromobenzaldehyde include: synthesis of aza-fused polycyclic quinolines through copper-catalyzed cascade reaction, preparation of 1-substituted indazoles by CuI-catalyzed coupling with N-aryl hydrazides.
