A new method for the cyanation of thiols and disulfides using cyanobenziodoxol(on)e hypervalent iodine reagents is described. Both aliphatic and aromatic thiocyanates can be accessed in good yields in a few minutes at room temperature starting from a broad range of thiols with high chemioselectivity. The complete conversion of disulfides to thiocyanates was also possible. Preliminary computational

Utilization of the GoAggIV system in the presence of sodium azide, sodium nitrite, sodium thiocyanate, sodium disulfide and tetraethylamonium cyanide converts saturated hydrocarbons into the corresponding alkyl azides, nitroalkanes, alkyl thiocyanates, dialkyl disulfides and alkyl cyanides, respectively. Mechanistic studies suggest an Fe-centered ligand coupling reaction pathway.

4-Aminophenyl Diphenylphosphinite (APDPP) as a Heterogeneous and Acid Scavenger Reagent for Thiocyantion or Isothiocyanation of Alcohols and Protected Alcohols
4-Aminophenyl diphenylphosphinite (APDPP) as a heterogeneous phosphinite reagent is used for the efficient conversion of alcohols, trimethylsilyl- and tetrahydropyranyl ethers, α -hydroxy phosphonates, and α -trimethylsilyloxyphosphonates to their corresponding thiocyanates or isothiocyanates in the presence of Br 2 and NH 4 SCN.

Reaction of p-toluenesulphonyl cyanide or methanesulfonyl cyanide with carbon radicals, generated from the corresponding O-acyl-N-hydroxy-2-thiopyridone derivatives by visible light photolysis gives nitriles in good yield. The homolysis products of these sulfonyl nitriles can also be trapped by electron rich olefins. We have also found that carbon radicals react easily with mesyl or tosyl isothiocyanate
