N-o-Nitrophenylthio-amino-acids were prepared in high yield by treatment of amino-acids with o-nitrophenyl-sulphenyl thiocyanate, a very stable compound, in the presence of silver nitrate. This reagent reacted selectively with lysine to give Nα-mono-o-nitrophenylthio- and NαNε-bis-o-nitrophenylthio-lysine with virtually none of the Nε-monosubstituted isomer. o-Nitrophenylsulphenyl p-nitrophenolate
