2,3-Dichloro-5,6-dicyano-1,4-benzoquinone synthesis

6synthesis methods
The first synthesis of 2,3-Dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) was described by J.Thiele and F.Guntber in 1906. However, no interest was shown in the compound until Linstead and co-workers discovered its extraordinary potency as a dehydrogenating agent. Its oxidation potential is greater than that of any other known quinone.

Yield:-

Reaction Conditions:

in methanol at 20; for 0.75 h;Equilibrium constant;

Steps:

2.2. Synthesis of charge transfer complexes of Ris drug donor

General procedure: The six risperidone solid charge transfer complexes with general formula [(Ris)(π-acceptor)] were synthesized as a solid colours, by mixing a (0.25 mmol, 0.103 g) of risperidone drug in 20 ml methanol to a 0.25 mmol of each acceptors; PA (0.06 g), DDQ (0.06 g), TCNQ (0.051 g), TCNE (0.032 g), p-BL (0.105 g) and p-CL (0.061 g) in 20 ml methanol solvent. All mixtures were stirred for 45 min at room temperature and the solid products were filtered off, washed with minimum amounts of chloroform and dried under vacuum over anhydrous CaCl2
