A waste-minimized protocol for copper-catalyzed Ullmann-type reaction in a biomass derived furfuryl alcohol/water azeotrope

We report the use of biomass-derived furfuryl alcohol as an effective bidentate ligand able to promote the Ullmann-type copper-catalyzed coupling of aryl halides with heteroaromatic or aliphatic amines.

Searching for novel reusable biomass-derived solvents: furfuryl alcohol/water azeotrope as a medium for waste-minimised copper-catalysed azide–alkyne cycloaddition

Herein we report the first application of the furfuryl alcohol/water azeotrope as a sustainable and easily recoverable reaction medium for organic chemistry. As first applicantion we have defined a waste-oinimized protocol for click-chemistry synthesi of 1,2,3-triazoles.

Shortened aerogel fabrication times using an ethanol–water azeotrope as a gelation and drying solvent

Native and cross-linked aerogel monoliths were fabricated in a few hours using a technique that does not require solvent exchange prior to supercritical drying.
