The reactivity of Bunsen's cacodyl disulfide, Me 2 As(S)‐S‐AsMe 2 , towards nitrogen, phosphorus(III), oxygen and sulfur(II) nucleophiles was evaluated with the aim at identifying its electrophilic atom. The nitrogen nucleophiles either did not react or bind or split the disulfide. All phosphorus(III) nucleophiles desulfurized it. Water, methanol and phenol did not react but thiophenol reacted giving an equilibrated system. The anions MeO – , PhO – and PhS – split the disulfide. From the results obtained it seems that the arsenic and sulfur of the As = S group are the most likely electrophilic atoms depending on the nature of the nucleophile, the As III being much less reactive in the presence of As=S.
