Abstract

The oxidation of benzyl halides to aldehydes with bismuth nitrate pentahydrate in an ionic liquid was studied. Also, an efficient one-pot synthesis of 3,4-dihydropyrimidin-2(1H)-ones from benzyl halides using bismuth nitrate pentahydrate in tetrabutylammonium fluoride (TBAF) as an in situ oxidant and catalyst is described.
