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 Luminescent Organic Liquids

Angewandte Chemie International Edition, 2012
Illuminating! 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 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.
