The synthesis of pyran-annulated heterocyclic systems, 2.9.3 (Scheme 11) can be carried out from various alicyclic/heterocyclic 1,3-dione, 2.9.1, and tetracyanoethylene, 2.9.2, using ecofriendly Ti[O.sub.2] and Ti[O.sub.2] nanoparticles as a catalyst with high yield.
In the current study, clusters C24H12 and C54H18 are used to model a graphene layer, and a variety of benzene derivatives and electron-donor/acceptor molecules such as tetracyanoethylene (TCNE), tetracyanoquino-dimethane (TCNQ), 2,4,7-trinitrofluorenone (TNF), tetrathiafulvalene (TTF), and N,N-dimethyl para-phenyienediamine (DMPD) are chosen to get the effect of substituent on the noncovalent interaction between graphene layer and aromatic molecules.
The cocatalyst has a double bond, electron-depleted by an electroattractive group including o-chloranyl (3,4,5,6-tetrachloro-1,2-benzoquinone), p-chloranyl (2,3,5,6-tetrachloro-1,4-benzoquinone), nitrobenzene, trinitrobenzene, or tetracyanoethylene. The final catalyst system consists of the initiator, a catalyst, and a cocatalyst.
The plastic magnet is made from a polymer comprised of tetracyanoethylene (TCNE) combined with manganese (Mn) ions (atoms of the metal with the electrons removed).
Miller says he was astonished when he and his colleagues mixed a vanadium compound into tetracyanoethylene, a carbon-nitrogen-based polymer, and found that it remained magnetic at temperatures much higher than any previous organic-based magnet.
In this study, we report a method to introduce abundant nitrile groups to pristine graphene by cycloaddition reaction of graphene with tetracyanoethylene oxide [18-20] (TCNEO) Scheme 1).
Graphene and tetracyanoethylene oxide were mixed and dispersed in 1, 2-dibromoethane, followed by continuous reactions at 140[degrees]C for 12 h in the N2 atmosphere.
One ingredient is an organometallic compound called decamethylferrocene; the other is tetracyanoethylene. The ferrocene molecule (the donor) readily transfers an electron to a tetracyanoethylene molecule (the acceptor), leaving each component with an unpaired electron.
The ESR spectrum of [[Cu(LH)].sub.2] in DMSO at 77 K has been recorded in X-band, using 100 kHz field modulation, and the g values are relative to the standard marker tetracyanoethylene (TCNE) (g = 2.0028).
