Solvent‐Free Passerini Reactions

Synthetic Communications, 2008
The influence of the substrate structure and concentration on the yield of the Passerini reaction was studied. A new, solvent-free methodology for a convenient preparation of alpha-acyloxyamides 4 was established and compared to the classical methodology. A higher reaction yield was obtained in shorter time, especially in the case of aromatic aldehydes.

Solvent-free synthesis of metal complexes

Chemical Society Reviews, 2007
Avoiding 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.

Illuminating solvent-free synthesis of zeolites

Dalton Transactions, 2020
Solvent-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 Organic Syntheses

Angewandte Chemie International Edition, 1998
Ecological points of view must nowadays be taken into consideration in the development of new syntheses and apportioned due importance in assessing the viability of a new synthesis. A crucial factor here is the need to restrict the use of ecologically harmful organic solvents.

Solvent-Free Process to Esterify Polysaccharides

Biomacromolecules, 2005
A 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.
