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.
Key words
dihydropyrimidinones - benzyl halides - oxidation-cyclocondensation - Bi(NO3)3·5H2O-TBAF - ionic liquid
