An N-heterocyclic carbene-catalyzed switchable reaction of 9-(trimethylsilyl)fluorene and aldehydes: Chemoselective synthesis of dibenzofulvenes and fluorenyl alcohols

An N-heterocyclic carbene-catalyzed synthesis of dibenzofulvenes and fluorenyl alcohols was developed. In the presence of 10 mol% NHC (1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) and 4 ? molecular sieves, 9-(trimethylsilyl)fluorene undergoes an olef

Effect of Bulky Size of Carbonyl Systems on Betaine Decomposition of Semi-stablized Arsonium Ylids

Reactions of substituted benzylidentriphenylarsenanes (2a-i) with 9-anthraldehyde and 9-fluorenone have been studied using benzene-sodamide, chloroform-sodium hydride and methanol-sodium ethoxide as solvent-base pairs.In all the cases olefins (5a-i and 6a-i) are formed exclusively.Variation of solvents and bases has no effect on the course of betaine decomposition formed by the nucleophilic attack of ylids on carbonyl systems.
