dicyanoの例文

• Poly ( 4, 4-dioctylcyclopentadithiophene ) can be doped with iodine or 2, 3-dichloro-5, 6-dicyano-1, 4-benzoquinone ( DDQ ) to form a transparent conductor.
• The usual method for selective cleavage of a PMB ether in the presence of a benzyl ether is through the use of strong stoichiometric oxidants such as 2, 3-dichloro-5, 6-dicyano-1, 4-benzoquinone ( DDQ ) or ceric ammonium nitrate ( CAN ).
• Therefore, the ?-keto thioester is formed out of the alcohol by a quadruplet of reactions with respectively 2, 3-dichloro-5, 6-dicyano-1, 4-benzoquinone ( DDQ ) treatment, this ?-keto thioester can be converted into an unstable diol, which is the acyclic precursor of the end product.
• A classical organic synthesis of this compound starts from a Birch reduction of naphthalene to tetrahydronaphthalene ( or isotetralin ), is followed by carbene addition of dichlorocarbene ( prepared in-situ from chloroform and the potassium salt of " tert "-butanol ) followed by a second organic reduction that removes the chloride substituents and is concluded by the organic oxidation by 2, 3-dichloro-5, 6-dicyano-1, 4-benzoquinone ( DDQ ).
