Abstract A novel series of transition metal complexes of Mn(II), Fe(III) Co(II), Ni(II), Cu(II), and Sb(III) containing the bidentate Schiff base derived from condensation of S-methyldithiocarbazate and cinnamaldehyde were synthesized and characterized by

Aldehydes and ketones were converted into 2-methylsulfinyl-5,6-dihydro-4H-1,3,4-thiadiazines via the formation and base-induced ring-closure of N-alkylidene-N′-bis(alkylthio)methylenehydrazines followed by mCPBA oxidation. The subsequent Pummerer-type ring fission of the rings was performed by treating with trifluoroacetic anhydride or trifluoromethanesulfonic anhydride at -78°C to give α,β-unsaturated esters and ketones in modest yields. Thus, this reaction sequence was regarded as being a new method for the two-carbon homologation of aldehydes and ketones.
