The current review deals with the use of ring expansion reactions for the synthesis of sulfur-
containing heterocycles. Ring enlargement offers by far a convenient method for the …

A systematic exploration of thiophilic ability of o-iodoxybenzoic acid (IBX) for oxidative
desulfurization to trigger domino reactions leading to new methodologies for synthesis of …

This review covers the synthetic applications of 1, 4-dithianes, as well as derivatives thereof
at various oxidation states. The selected examples show how the specific heterocyclic …

The reaction of aldehydes, amines, and TMSCN in the presence of 2-iodoxybenzoic acid
(IBX) and tetrabutylammonium bromide (TBAB) afforded α-iminonitriles in good to excellent …

A clean and efficient method for the oxidative transformations of primary carboxamides to
one-carbon dehomologated nitriles using the combination of o-iodoxybenzoic acid and …

Thio migration has emerged as a valuable synthetic tool for organic chemists. The most
common route of 1, 2-thio migration proceeds through a thiiranium intermediate. The latter …

Novel and facile transformation of N, N-disubstituted glycylamides into corresponding
cyanamides using pentavalent iodine reagents and tetraethylammonium bromide is …

Base-mediated rearrangement of 1, 3-dithianyl-substituted propargylamines in DMF via
expansion of the dithiane ring has been reported. The rearrangement provided 9-membered …
