Tris(pentafluorophenyl)borane-Catalyzed Acceptorless Dehydrogenation of N-Heterocycles.

Angewandte Chemie, 2016
Catalytic acceptorless dehydrogenation is an environmentally benign way to desaturate organic compounds. This process is traditionally accomplished with transition-metal-based catalysts. Herein, a borane-catalyzed, metal-free acceptorless dehydrogenation

Synthesis of 1,1,1-Tris(boronates) from Vinylarenes by Co-Catalyzed Dehydrogenative Borylations-Hydroboration.

Journal of the American Chemical Society, 2015
The selective preparation of 1,1,1-tris(boronates) from vinylarenes and bis(pinacolato)diboron is described. The reactions occur at ambient temperature with excellent selectivity, high yields, and good functional group tolerance.

Tris buffer modulates polydopamine growth, aggregation, and paramagnetic properties.

Langmuir, 2014
Despite the growing technological interest of polydopamine (dopamine melanin)-based coatings for a broad variety of applications, the factors governing particle size, shape, and electronic properties of this bioinspired multifunctional material have ...

Neither delta- nor lambda-tris(phenanthroline)ruthenium(II) binds to DNA by classical intercalation.

Biochemistry, 1992
Equilibrium binding studies and viscosity experiments are described that characterize the interaction of delta- and lambda-[Ru(o-phen)3]2+ with calf thymus DNA. The mode of binding of these compounds to DNA is a matter of controversy. Both isomers of [Ru(

Tris(phenanthroline)ruthenium(II) enantiomer interactions with DNA: mode and specificity of binding.

Biochemistry, 1993
Absorbance and fluorescence methods, circular dichroism, UV melting experiments, viscosity, and competition dialysis were used to study the interaction of delta and lambda tris(phenanthroline)ruthenium(II) with DNA. The results of these studies indicated

Fluorescent tris-imidazolium sensors for picric acid explosive.

Journal of Organic Chemistry, 2013
Two new anthracene-functionalized fluorescent tris-imidazolium salts have been synthesized, characterized, and proven to be selective sensors for picric acid, which is a common constituent of many powerful explosives.

Tri and tri again

Nature Physics, 2011
Monolayer graphene is a semimetal with no bandgap, and bilayer graphene is a semiconductor with a tunable gap. A trio of studies now shows that trilayer graphene can be either, depending on how its layers are stacked — behaviour that could support exotic new electronic states.

Synthesis of a rigid C3v -symmetric tris-salicylaldehyde as a precursor for a highly porous molecular cube.

Chemistry, 2014
The development of a synthetic approach to a C3v -symmetric tris-salicylaldehyde based on triptycene is presented. The tris-salicylaldehyde is a versatile precursor for porous molecular materials, as demonstrated in the [4+4] condensation reaction with a
