The synthesis of a number of novel dibenzene-1,2-diol Mannich bases can be achieved in good yields by the condensation of 2-methoxyphenol, formaldehyde and secondary diamines. The newly developed synthetic method utilizes 2-methoxyphenol instead of benzene-1,2-diol providing a useful tool for greater control over reaction products.

Disclosed herein are lignin-derived ionic liquids and methods for preparing them. The methods include forming a reaction mixture comprising a lignin-derived starting material, a carbonyl compound, and an amine; maintaining the reaction mixture under conditions sufficient to form a lignin-derived aminophenol; and converting the lignin derived aminophenol to the lignin-derived ionic liquid. Monomeric phenols, oligomeric phenols, and polymeric phenols can be used as lignin-derived starting materials.
