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 di
Various cinnamate derivatives were tested as inducers for reduction of C–C 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 ...
摘要: Double bonds activated by the electron withdrawing group(s) are cleaved with the reagent system consisting of a hard Lewis acid and ethanethiol to give dithioacetals.关键词: thio compounds (benzene compounds DOI: 10.1016/0040-4039(81)80019-6 ...
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...
An ester derivant having a crystal structure in which the molecules in two adjacent molecule planes are antiparallel is created from a carboxylic acid having carbon-carbon double bond and a compound having a functional group that can rea... A Matsumoto,T Tanaka 被引量: 1发表: 2008年 Photosens...
A survey of carbon–carbon double bond lengths in transition metal vinyl complexes reveals a number of complexes with surprisingly short C C bonds. Accurate calculations with restricted Hartree–Fock (RHF) and density functional theory (DFT) methods on three examples with extremely short C C double...
Such influence causes the transformation of the sp2-carbon bond to the sp3-state. The high electronegativity induced by fluorine-doping enhances Na+ ion transportation and storage by weakening the repulsive force for Na+ ion insertion and removal. This phenomenon reduces the energy barrier for Na+...
(III) that would otherwise disproportionate. Thus, rather than the arene being the functional group focus, here it is overtly performing a role as an ancillary, facilitating ligand to stabilise another metal-ligand functional unit. These ‘two-dimensional’ polyuranium complexes also demonstrate that...
These fatty acids have their first double carbon bond at the third hydrocarbon from the methyl group (referred to as the omega end of the molecule).Finally, trans fatty acids found in some processed foods, including some stick and tub margarines, are thought to be even more harmful to the...
