trans-1,3,3,3-Tetrafluoropropene (HFO-1234ze(E), R-1234ze(E)) is a hydrofluoroolefin. It was developed as a "fourth generation" refrigerant to replace fluids such as R-134a , as a blowing agent for foam and aerosol applications, and in air horns and gas dusters . [ 3 ]
One attractive feature of the Peterson olefination is that it can be used to prepare either cis- or trans-alkenes from the same β-hydroxysilane. Treatment of the β-hydroxysilane with acid will yield one alkene, while treatment of the same β-hydroxysilane with base will yield the alkene of opposite stereochemistry.
Thus, the two substrates of this enzyme are cis-3-phenylcyclohexa-3,5-diene-1,2-diol and NAD +, whereas its 3 products are biphenyl-2,3-diol, NADH, and H +. This enzyme belongs to the family of oxidoreductases , specifically those acting on the CH-CH group of donor with NAD+ or NADP+ as acceptor.
For ML a 4 L b 2, two isomers exist.These isomers of ML a 4 L b 2 are cis, if the L b ligands are mutually adjacent, and trans, if the L b groups are situated 180° to each other. It was the analysis of such complexes that led Alfred Werner to the 1913 Nobel Prize–winning postulation of octahedral complexes.
The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another. [1] The chemical bonding within the molecule is also shown, either explicitly or implicitly.
Structure of a trisubstituted hexahydrotriazine. In chemistry, hexahydro-1,3,5-triazine is a class of heterocyclic compounds with the formula (CH 2 NR) 3. Known as aldehyde ammonias, these compounds characteristically crystallize with water. They are reduced derivatives of 1,3,5-triazine, which have the formula (CHN) 3, a family of aromatic ...
The skeletal formula of the antidepressant drug escitalopram, featuring skeletal representations of heteroatoms, a triple bond, phenyl groups and stereochemistry. The skeletal formula, line-angle formula, bond-line formula or shorthand formula of an organic compound is a type of molecular structural formula that serves as a shorthand representation of a molecule's bonding and some details of ...
