Aerobic oxidation of thiols to disulfides has been carried out using iron metalâorganic frameworks (MOFs) as solid redox catalysts with very high yield and selectivity in acetonitrile under mild reaction conditions.

Copolymericsuccinamicacid (COSMA) additives have been synthesised in the laboratory and evaluated for their antiwear performance, both alone and in combination with zinc dialkyl-dithiophosphate (ZDDP) in HVI light neutral oil. COSMA additives show antiwear behaviour and, in combination with ZDDP, exhibit a good synergistic effect, reducing the wear-scar diameter by 60% and increasing the initial
We describe a novel disulfide reaction via UV/DMAP methodology for efficient construction of simple disulfides and structurally complex peptides.

Thiols are efficiently oxidized to disulfides (RSSR) in presence of 3, 6-Di(pyridin-2-yl)-1,2,4,5-tetrazine (pytz) in aqueous medium, as well as in absence of solvent under mild and metal-free conditions. A broad...
