Various cinnamate derivatives were tested as inducers for reduction of C鈥揅 double bonds in Acetobacterium woodii. The double bond and a phenyl ring were essential for induction, since crotonate and hydrocaffeate were ineffective as inducers whereas cinnamate derivatives were effective. Induction was...
Inorganic nanocrystals surface-coordinated with a compound containing a photosensitive carbon to carbon double bond functional group is used for photolithographic process to form a pattern; curable with a curing agents; photomasking; simple method; organic-inorganic hybrid electroluminescent devicesUS 7476487...
Regioselective vicinal diamination of carbon–carbon double bonds with two different amines is a synthetic challenge under transition metal-free conditions, especially for the synthesis of trifluoromethylated amines. However, the synthesis of ethylene diamines and fluorinated amine compounds is demanded, es...
An sp2-hybridized orbital and a p-orbital that is not involved in the hybridization form a double bond, while a triple bond evolves from an sp-hybridized orbital and two p-orbitals from each atom. The use of the p-orbitals forms a pi (π) bond. Understanding the hybridization of its ...
melt kneading polyethylene, compound having in its molecule at least one carbon-carbon double or triple bond and polar group, or compound having in its molecule an OR group and two specific functional groups and organic peroxide having decomposition temperature of 50-115 degrees C; for graftingUS...
β-double bond in the four-membered ring could easily migrate to the β,γ-carbons. Placing a substituent (such as a CH3or Cl unit) at the α-carbon of1led to nearly no reaction, and the ketone substrate was recovered under the reaction condition. The β-aryl group of1could be ...
... Carcinogens that are easily oxidizable can be destroyed with milder oxidative agents, such as saturated soln of potassium permanganate in acetone, which appears to be a suitable agent for destruction of hydrazines or of compounds containing isolated carbon-carbon double bonds. Concn or 50% ...
implying their same type and content of surface-absorbed functional groups. Figure5e–g are XPS spectra of C, N, and O elements captured from EDCF-3, EDCF-7, and EDCF-8 samples. In Fig.5e, it can be observed that the integral area of C–C/C–O band and C=O/C=N bond slightly...
the position of G band gradually shifts from 1510 to 1600 cm−1and the profile of G band becomes relatively narrow, and meanwhile, an incrementalID/IGvalue from 0.25 to 2.0 can be also detected. These changes are attributed to the decreased disorders in bond angle and bond bending, as we...
Figure 1. Catalytic methods for carbon–carbon bond cleavage (A) Functional groups may be added at thermodynamically activated or kinetically preferred positions. (B and C) Saturated hydrocarbons in small molecules and polymers may be shorted by alkane metathesis (B) or nanoparticle or early-metal ...
