Solvent-Free Routes to Clean Technology

Chemistry - A European Journal, 2001
A 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 aziridination of α-nitroalkenes

Tetrahedron, 1998
Abstract 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 ...

Solvent-free

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 Synthesis of Microparticles on Superamphiphobic Surfaces

Angewandte Chemie International Edition, 2013
Polymeric 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 Reactions

1999
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 Protein Liquids and Liquid Crystals

Angewandte Chemie International Edition, 2009
Nanostructures 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 ...
