Silphox [POCl3−n (SiO2) n ] as a new, efficient and heterogeneous reagent for the preparation of N-sulfonyl imines under solvent-free conditions

An efficient, simple and clean solvent-free procedure for the preparation of N-sulfonyl imines is described. The reaction of sulfonamides with different aromatic aldehydes in the presence of silica-phosphinoxide (Silphox) [POCl 3−n (SiO 2 ) n ] as a new and heterogeneous reagent affords the title co...

Summary:An efficient, simple and clean solvent-free procedure for the preparation of N-sulfonyl imines is described. The reaction of sulfonamides with different aromatic aldehydes in the presence of silica-phosphinoxide (Silphox) [POCl 3−n (SiO 2 ) n ] as a new and heterogeneous reagent affords the title compounds in good to high yields.
