Ionic liquid anchored to silica (nano-SB-[PSIM]Cl): a highly efficient nanocatalyst for the solvent-free preparation of 1-thioamidolakyl-2-naphthols
Volume 8, Issue 1 , January 2020, , Pages 49-57
Abstract
Nano-silica-bonded 3-n-propyl-1-sulfonic acid imidazolium chloride (nano-SB-[PSIM]Cl) was applied as a highly efficient, general and heterogeneous catalyst for one pot multi-component reaction of 2-naphthol, arylaldehydes, and thioacetamide leading to 1-thioamidolakyl-2-naphthols. All reactions proceeded ...

A green and highly effective protocol for the synthesis of N,N′-alkylidene bisamides using saccharin-N-sulfonic acid
Volume 8, Issue 1 , January 2020, , Pages 58-66
Abstract
A green and highly effective solvent-free protocol has been reported for the synthesis of N,N′-alkylidene bisamides via the reaction of arylaldehydes (1 eq.) with primary amides (2 eq.) in the presence of saccharin-N-sulfonic acid (SaSA) as a solid-acid catalyst. The mentioned compounds have been ... Read More)
