Caratterizzazione ed isolamento di intermedi delle reazioni di sostituzione elettrofila e nucleofila in serie aromatica
1,3,5–Tris(N,N-dialkylamino)benzene derivatives are strongly activated neutral carbon nucleophiles able to stress some reactivity aspects toward more or less activated electrophilic substrates. These very interesting electron-rich benzenes have been firstly synthesized in 1967 and extensively …

Design and Synthesis of Estrogen Receptor Coactivator Binding Inhibitors
… variety of core scaffolds including amphipathic benzene, bicyclo[2.2.2]octane, and urea, resulting in three different series of compounds that could be utilized as coactivator binding inhibitors (CBIs). A fluorescence-based assay was used to evaluate the ability of the CBIs to effectively block …

Temperature Programmed Desorption and Infrared Spectroscopic Studies of Interfacial Hydrogen Bonds for Small Molecules Adsorbed on Silica and Within Metal Organic Frameworks
… bond, the adsorption of simple substituted benzene derivatives on silica was investigated to probe the effects of electron withdrawing and donating substituents. Results indicate that the substituted benzene derivatives adsorb to silica via a cooperative effect involving SiOH---π hydrogen …

Directed Ortho-Metalation of Dimethylarylamines
Site-specific product(s) from the reaction of benzene derivatives with various reagents is a need of researchers at numerous laboratories, particularly those in the pharmaceutical industry. Such derivatives can be synthesized directly, i.e., by substitution of a proton, using either of two …

Time Dependent Uptake of Volatile Organic Compounds on Silica and the Observation and Quantification of Ambient Sesquiterpenes in Virginia
… of two classes of compounds: singly substituted benzene derivatives and several terpenoid compounds for a silica surface composed of hydroxyl groups and bridging oxygen species. Results for benzene derivatives show an enhancement of the initial γ value of all functionalized compounds relative to …

cis-Arenediols as versatile chiral synthons in the synthesis of prostaglandins, cyclitols, carbohydrates, and alkaloids
The oxidation of simple benzene derivatives by a mutant of Pseudomonas putida, called 39-D, produces cis-arenediols (1). The diols are enantiomerically pure and can be used as synthons for the preparation of a variety of interesting compounds because of their stereochemistry and the special array …

Polyfluorinated Aromatic Systems for Liquid Crystal Display Applications
… of a range of polyfluorinated biphenyl ether derivatives for use as dopants in commercial LC materials, so that overall display performance may be improved. Reactions of hexa– and penta–fluorobenzene with sodium phenoxide in polar aprotic solvents (MeCN, THF) and under mild reaction conditions …

Single Molecule Junction Conductance and Binding Geometry
… and electronic properties of an amine-terminated benzene derivative on gold. We find that details of metal-molecule binding affect energy-level alignment at the interface. Next, using the STM-BJ technique, we form and rupture metal-molecule-metal junctions ~104 times to obtain …
