Reactions using fluorous reagents and scavengers are compared side-by-side with their solid-supported counterparts. Fluorous triphenylphosphine is used in the bromination reaction of alcohols, fluorous thiol is used as an electrophile scavenger for alpha-bromoketones, fluorous isatoic anhydride is used as a

A novel one-pot tandem synthesis of 2-styryl-4(3 H)-quinazolinones in an acidic ionic liquid is reported. In this procedure isatoic anhydride, a primary aniline or ammonium acetate, and triethylorthoacetate are reacted in the presence of imidazolium trifluoroacetate [Hmim]TFA. Subsequently an aromatic
