Illuminating solvent-free synthesis of zeolites
Dalton Transactions, 2020Solvent-free synthesis of zeolites is industrially efficient and sustainable with unique advantages such as morphological control, construction of hierarchical porosity, and organotemplate-free synthesis of siliceous zeolites.

Solvent-free biodiesel epoxidation
Environmental Chemistry Letters, 2013Biodiesel emerged again recently as an alternative for fossil fuels. Besides energy, biodiesel can be used as raw material to synthesize high value products such as epoxides. Indeed, epoxides are versatile intermediates in organic synthesis for numerous reactions due to the high reactivity of the oxirane ring. Actually common epoxidation by peracids in

Solvent-Free Process to Esterify Polysaccharides
Biomacromolecules, 2005A novel process for the preparation of acetates of polysaccharides is described herein. The process involves the acetylation of polysaccharides with acetic anhydride in the presence of iodine as a catalyst. No solvent is required to bring about the acetylation. The method is simple, rapid, and characterized by a high conversion ratio.

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 metal complexes
Chemical Society Reviews, 2007Avoiding the use of solvents in synthesis can reduce environmental contamination and even be more convenient than using solvent-based synthesis. In this tutorial review we focus on recent research into the use of mechanochemistry (grinding) to synthesise metal complexes in the absence of solvent.

Solvent free catalytic C–H functionalisation
Chemical Communications, 2010Solvent-free reaction conditions facilitate a range of aromatic C-H functionalisations that traditionally require acidic or disfavoured solvents. These reactions include selective ortho- and meta-arylation of aryl carbamates and anilides and selective halogenation 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 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 ...

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 ...
