The article was titled 《Facile Synthesis of Highly Congested 1,2-Diphosphinobenzenes from Bis(phosphine)boronium Salts》.Application In Synthesis of Ethyl 3-(4-chlorophenyl)propanoate The article contains the following contents:
Bis(phosphine)boronium salts were designed and prepared as key building blocks for the synthesis of highly congested diphosphinobenzenes. The preparation of sterically hindered ortho-phenylene-bridged diphosphines, e.g. 1,2-C6H4[P(Bu-t)2]2 (I), was achieved by the reaction of the bis(phosphine)boronium salts with difluorobenzenechromium complex and subsequent removal of the BH2 group. The steric nature of diphosphine I was revealed in single-crystal x-ray anal. of its Rh complex. After reading the article, we found that the author used Ethyl 3-(4-chlorophenyl)propanoate(cas: 7116-36-1Application In Synthesis of Ethyl 3-(4-chlorophenyl)propanoate)
Ethyl 3-(4-chlorophenyl)propanoate(cas: 7116-36-1) belongs to organochlorine compounds. Many organochlorine compounds have been isolated from natural sources ranging from bacteria to humans. Application In Synthesis of Ethyl 3-(4-chlorophenyl)propanoate Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids.
