So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Yuan, Jing; Liu, Chong; Chen, Yan; Zhang, Zhenfeng; Yan, Deyue; Zhang, Wanbin researched the compound: Bis(norbornadiene)rhodium (I) tetrafluoroborate( cas:36620-11-8 ).Formula: C14H8BF4Rh.They published the article 《Rhodium-catalyzed intramolecular hydroacylation of 1,2-disubstituted alkenes for the synthesis of 2-substituted indanones》 about this compound( cas:36620-11-8 ) in Tetrahedron. Keywords: indanone preparation rhodium catalyst intramol hydroacylation disubstituted alkene. We’ll tell you more about this compound (cas:36620-11-8).
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.
In some applications, this compound(36620-11-8)Formula: C14H8BF4Rh is unique.If you want to know more details about this compound, you can contact with the author or consult more relevant literature.
