Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 36620-11-8, is researched, Molecular C14H8BF4Rh, about Rhodium-catalyzed intramolecular hydroacylation of 1,2-disubstituted alkenes for the synthesis of 2-substituted indanones, the main research direction is indanone preparation rhodium catalyst intramol hydroacylation disubstituted alkene.Recommanded Product: Bis(norbornadiene)rhodium (I) tetrafluoroborate.
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.
