The Leuckart thiophenol reaction is the decomposition of a diazoxanthate, by gentle warming in a slightly acidic cuprous medium, to its corresponding aryl xanthates which give aryl thiols on alkaline hydrolysis and aryl thioethers on further warming.[1]

Reaction pathway and mechanism

This reaction was first reported by Rudolf Leuckart in 1890.[2][3][4]
