General description

3,4-Diaminotoluene on treatment with [{PhP(Se)(μ-Se)}2], causes the rupture of the dimer, giving PhP(Se)(NHC6H3(CH3-3)NH-1,2).

Application

3,4-Diaminotoluene was employed as catalyst for the two-step reduction of Zn(II) ions at dropping mercury electrode in 1M NaClO4 + 0.001M HClO4. It was also used in the synthesis of new benzimidazole derivatives with cyclohexylalkyl and aralkyl substituents in position 2.
