Yuan, Jing; Liu, Chong; Chen, Yan; Zhang, Zhenfeng; Yan, Deyue; Zhang, Wanbin published an article about the compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate( cas:36620-11-8,SMILESS:[F-][B+3]([F-])([F-])[F-].C12=C3[Rh+]14567(C8=C5C9C6=C7C8C9)C%10=C4C2CC3%10 ).Formula: C14H8BF4Rh. Aromatic heterocyclic compounds can be classified according to the number of heteroatoms or the size of the ring. The authors also want to convey more information about this compound (cas:36620-11-8) through the article.
The intramol. hydroacylation of 1,2-disubstituted alkenes was considered to be a challenging task due to the side reactions resulted from the lack of addnl. substituent at 1-position and the low activity caused by the steric hindrance of substituent at 2-position, and an asym. version was not considered possible due to problems associated with the racemization of the products. The authors have partially solved these problems. Catalyzed by an activated diphosphine-Rh complex and reacted in a selected dihalogenated solvent, the intramol. hydroacylation of o-(2-arylvinyl)benzaldehydes provided the corresponding 2-aryl-1-indanones in high yields, and its asym. variant using o-(2-alkylvinyl)benzaldehydes afforded chiral 2-alkyl-1-indanones in high yields and with moderate enantioselectivities.
I hope my short article helps more people learn about this compound(Bis(norbornadiene)rhodium (I) tetrafluoroborate)Formula: C14H8BF4Rh. Apart from the compound(36620-11-8), you can read my other articles to know other related compounds.
