Anodic fluorination of dithioacetals bearing electron-withdrawing ester, acetyl, amide, and nitrile groups at their α-positions was comparatively studied using various supporting poly(HF) salts like Et3N·nHF (n = 3-5) and Et4NF·nHF (
Isothiourea-mediated one-pot synthesis of trifluoromethyl substituted 2-pyrones

A one-pot isothiourea-mediated Michael addition/lactonization/thiol elimination cascade sequence for the formation of 4,6-disubstituted and 3,4,6-trisubstituted 2-pyrones from (phenylthio)acetic acids and α,β-unsaturated trifluoromethyl ketones is described. The synthesis of a COX-2 inhibitor and the wide-ranging derivatization of the 2-pyrone moiety to trifluoromethyl substituted aromatics and heteroaromatics is also disclosed.
Novel Alumina-catalysed Reactions of Arylthioalkyl Halides and Related Compounds

Arylthioalkyl halides of the type ArS(CH2)nCl (Ar = phenyl or substituted phenyl, n = 1-4) undergo rearrangement on heating with neutral alumina to 1,n-bis(arylthio)alkanes of type ArS(CH2)nSAr in high yield.Similar rearrangements occur with some closely related structural types.The bis(arylthio)alkanes undergo further reaction with alumina at higher temperatures in air giving diaryl disulphides.Bis(o-iodophenylthio)methane eliminates iodine on heating with alumina, producing dibenzodithiepin.Some observations concerning the mechanism are presented.
A NOVEL AND CONVENIENT SYNTHESIS OF BISMETHANES

Bismethanes are produced in high yield on treatment of aryl chloromethyl sulphides with neutral alumina.
