In another variation the reagent is the imidazole 1, 1'- thiocarbonyldiimidazole ( TCDI ), for example in the total synthesis of pallescensin B . TCDI is especially good to primary alcohols because there is no resonance stabilization of the xanthate because the nitrogen lonepair is involved in the aromatic sextet.
