Oxalic acid-mediated conversion of alcohols to thiocyante and/or isothiocyanate is described. Aliphatic tertiary alcohols give isothiocyanate by the reaction with NaSCN in the presence of I2, whereas they give thiocyanate without it.

When tert-alcohols were treated with ( COOH) 2 and NaSCN in the presence of iodine, tertiary alkyl isothiocyanates were obtained in good yield, whereas the corresponding thiocyanates were obtained in low yield in the absence of iodine. (c) 2007 Elsevier Ltd. All rights reserved.
