Improved Syntheses of 1H-Benz[f]indene

Synthesis of zirconocenes bearing benz[f]indenyl ligand and their use as a catalyst in ethylene polymerization

“…Substituted benz [f]indenes [5] and unsubstituted benz [f]indene [7] were prepared by the procedure of the literature. The benz [f]indenes having substituents were not soluble in diethyl ether but soluble in THF at À78°C.…”

Heterogeneous Bifunctional Metal/Acid Catalysts for Selective Chemical Processes

“…[118] In a recent study, the selective synthesis of aryl olefins from the corresponding ketones was carried out in the liwww.eurjic.org quid phase in a one-pot process by tandem hydrogenationdehydration reactions.

Newly Identified Products of Benzene Droplet Combustion: Polycyclic Aromatic Hydrocarbons of Three to Ten Rings

“…Mobile phases of water/acetonitrile, acetonitrile, and dichloromethane (DCM) follow a preset time program that is activated by the sample injection. This method resolves individual PAH, which are then unequivocally identified by matching their HPLC retention times and UV absorbance spectra with those of commercially available reference compounds and specially synthesized reference standards (39)(40)(41)(42)(43)(44)(45)(46). Broadband diode-array UV detection also produces chromatographic signals which closely approximate mass concentrations (47,48), since the mass-based response factors for PAH vary little from compound to compound as long as the UV absorbance signal is integrated over the entire wavelength range in which the compounds absorb (47).…”
