Solvent effect in a “solvent free” reaction
CrystEngComm, 2007Vapour digestion of a mixture of solid [Fe(η5-C5H4–C5H4N)2] and solid pimelic acid HOOC(CH2)5COOH in the presence of solvent vapours generates co-crystals of different stoichiometry depending on the protic or aprotic nature of the solvent. The nature of the products has been ascertained by a combined use of SSNMR and X-ray diffraction.

Solvent-free aziridination of α-nitroalkenes
Tetrahedron, 1998Abstract NsONHCO 2 Et in the presence of CaO reacts without solvent with α-nitroalkenes to give 1-(ethoxycarbonyl)-2-nitroaziridines (62–84%). A possible involvement of an aza-Michael route is proposed on the basis of regio- and stereochemical reaction outcome, compared also with the results of thermolysis of ethyl azidoformate on the same α ...

For reasons of economy and pollution, solvent-free methods are of great interest in order to modernize classical procedures making them more clean, safe and easy to perform. Reactions on solid mineral supports, reactions without any solvent/support or catalyst, and solid-liquid phase transfer catalysis can be thus employed with noticeable increases in ...

Solvent‐Free Luminescent Organic Liquids
Angewandte Chemie International Edition, 2012Illuminating! Isolation of a π-core by covalently attached flexible hydrocarbon chains has been employed to synthesize blue-emitting oligo(p-phenylenevinylene) (OPV) liquids with tunable viscosity and optical properties. A solvent-free, stable, white-light emitting ink/paint, which can be applied onto various surfaces and even onto LEDs, was made by ...

Solvent-Free Functionalization of Carbon Nanotubes
Journal of the American Chemical Society, 2003A fundamentally new single-walled and multiwalled carbon nanotube sidewall functionalization technique has been developed in which solvent is not required and the reaction times are greatly shortened (1 h at 60 degrees C). Exploiting the long linear dimension of the nanotube ropes by macroscopic mechanical deformation, reactive sites are generated ...

Acta crystallographica. Section C, Crystal structure communications
The title compound, [Au(2)Cl(2)Fe(C(17)H(14)P)(2)], (I), contains the expected linear gold centres. The ferrocene moiety acts as a P, P'-bridging ligand, wherein the Fe atom lies on an inversion centre. The P-Au-Cl angle is 177.56 (8) degrees and bond distances Au-P and Au-Cl are 2.2261 (18) and 2.2781 (18) A, respectively.

Solvent-Free Routes to Clean Technology
Chemistry - A European Journal, 2001A major aim for the chemical technology of the future is the avoidance of noxious and environmentally unacceptable organic solvents. In this concept article we discuss more environmentally friendly and highly selective alternatives which we have evolved for carrying out a number of important chemical conversions.

Solvent‐Free Synthesis of Microparticles on Superamphiphobic Surfaces
Angewandte Chemie International Edition, 2013Polymeric and composite microspheres can be synthesized without solvents or process liquids by using superamphiphobic surfaces. In this method, the repellency of superamphiphobic layers to monomers and polymer melts and the extremely low adhesion to particles are taken advantage of.

Solvent‐Free Protein Liquids and Liquid Crystals
Angewandte Chemie International Edition, 2009Nanostructures such as functionalized nanoparticles and superlattices have wide-ranging applications in diverse areas. Although these materials are invariably used in the form of aqueous/organic dispersions, ultrathin films, or bulk powders, Giannellis and co-workers have recently pioneered an approach to preparing functionalized inorganic ...
