摘要
The ammonium metavanadate/thiocyanate system is used as an efficient reagent for regioselective thiocyanation of aromatic and hetero aromatic compounds under conventional and nonconventional conditions such as ultrasonically assisted and microwave-assisted reactions. The reactions proceeded smoothly and afforded good yields of products with high regioselectivity. Longer reaction times (about 8 h) observed under conventional conditions were reduced to 0.5 h/30 min under sonication and to 90 s in the case of microwave-assisted reactions. [GRAPHICS] .
