In 2004,Chemical Communications (Cambridge, United Kingdom) included an article by Moss, Rebecca J.; Wadsworth, Kelly J.; Chapman, Christopher J.; Frost, Christopher G.. Formula: C6H4BBrF3K. The article was titled 《Rhodium-catalyzed tandem conjugate addition-protonation: an enantioselective synthesis of 2-substituted succinic esters》. The information in the text is summarized as follows:
The rhodium-catalyzed addition of potassium trifluoro(organo)borates to di-Me itaconate generated an intermediate complex which on protonation provided enantioenriched succinic esters, e.g., I. After reading the article, we found that the author used potassium (3-bromophenyl)trifluoroborate(cas: 374564-34-8Formula: C6H4BBrF3K)
potassium (3-bromophenyl)trifluoroborate(cas: 374564-34-8) belongs to organobromine compounds. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact. Formula: C6H4BBrF3K
