Solvent-free multicomponent synthesis of 2-arylpyridines using p-sulfonic acid calix[6]arene as a reusable catalyst
(Comptes Rendus Chimie, 2018)
Synthesis of 1,5-benzodiazepines with unusual substitution pattern from chalcones under solvent-free microwave irradiation conditions
(2009)
1,5-Benzodiazepines have been synthesized from the corresponding 2'-hydroxychalcones [1-(2-hydroxyphenyl)-3-aryl-2-propen-1-ones] and o-phenylenediamine, both in methanol, under reflux and under solvent-free microwave ...
Solvent free esterification reactions using Lewis acids in solid phase catalysis
(Elsevier B.V., 2006-10-04)
A clean, efficient and fast method for esterification reactions for sterically (biodiesels) or otherwise inactive (aromatic) precursors was developed, using catalysts supported in a solid phase under solvent free conditions, ...

Solvent- and catalyst-free regioselective hydrophosphanation of alkenes
(Royal Society of Chemistry, 2012-10)
The hydrophosphanation of alkenes, an atom-economy process typically promoted by radicals or metal species, has been shown to take place in the absence of a catalyst, under solvent-free conditions and in a regioselective manner.
Influences of surface and solvent on retention of HEMA/mixture components after evaporation
(ELSEVIER SCI LTD, 2010)
Objectives: This study examined the retention of solvents within experimental HEMA/solvent primers after two conditions for solvent evaporation: from a free surface or from dentine surface. Methods: Experimental primers ...
Solvent-free multicomponent synthesis of 2-arylpyridines using p-sulfonic acid calix[6]arene as reusable catalyst
(Elsevier Masson, 2015-03-10)
An new and efficient methodology for obtaining 2-arylpyrimidines based on the use of psulfonic acid calix[6]arene as organocatalyst is proposed. The methodology involves the formation of 1,2-dihydropyridine intermediates ...
