ABSTRACT: Indoles, pyrrole aniline derivatives and aromatic amino compounds undergo smooth thiocyanation with cross-linked poly (4-vinylpyridine) supported thiocyanate ion, [P4-VP]SCN in the presence of ceric ammonium nitrate (CAN) as a versati

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.

A green and efficient regioselective thiocyanation of indoles, anilines and pyrrole has been achieved via a simple protocol using cross-linked poly (4-vinylpyridine) supported thiocyanate ion, [P4-VP]SCN, as a versatile polymeric reagent and ox
An efficient and regioselective thiocyanation of aromatic and heteroaromatic compounds using cross-linked poly (4-vinylpyridine)-supported thiocyanate as a versatile reagent and potassium peroxydisulfate as a strong oxidizing agent

, p. 458 - 469 (2014/06/10)
A green and regioselective thiocyanation of aromatic and heteroaromatic compounds has been achieved via a simple protocol using cross-linked poly (4-vinylpyridine)-supported thiocyanate ion, [P4-VP]SCN, as a versatile polymeric reagent and potassium persulfate as a strong oxidizing agent, under heterogeneous conditions.Various indoles, phenol and aniline derivatives, and pyrroles were transformed into their corresponding aryl thiocyanates in high to excellent yields. This procedure offers advantages such as short reaction time, simple reaction work-up, and the polymeric reagents can be regenerated and reused for several times without significant loss of their activity.
