All three compounds possess three-dimensional (3D) architectures. The adjacent carboxylate groups attached to the aromatic ring in the ligands result in strong steric hindrance, and, therefore, they are forced to orient themselves vertically to the aromatic ring. This conformation contributes to the ...
Vehicle distribution influences the contributions of organic group to OFP in a tunnel. Meanwhile, when ranked in descending order of contribution to OFP in all tunnels, the organic groups followed the sequence olefins, aromatics, and paraffins....
The equatorialequatorial (e,e) conformation is adopted commonly in all these compounds, although less stable conformations are encountered occasionally. The formation of the layered and the three-dimensional structures can be understood based on the relative disposition of the two carboxylic groups, the...
Control of regioselectivity and/or diasterioselectivity of the most products is related to micelle formation of organic substrates and SDS in water. Hydrophobic groups of substrates self-assembled in these microreactors whereas, hydrophilic groups were solvated with water or chelated with Mn(HSO4). ...
A mechanism for the formaldehyde elimination and scrambling of the methyl groups is proposed and supported by a kinetic analysis of a limiting case. During this study 'black holes' were found to occur in one of the ITMS instruments used and it is shown that these could lead to severe ...
Ground-state charge-transfer interactions have been examined for compounds 3a,b, 5a,bvia analysis of their crystal and molecular structures. It is significant that the vinyl group rotates out of the BC3 plane by 16.8° for 3a and 12.0° for 5a, whereas mesityl groups are typically rotated ...
Second, AACR reduces the acetoacetyl group of acetoacetyl-CoA and produces (R)-3-hydroxybutanoyl-CoA. Finally, PHAP polymerizes several (R)-3-hydroxybutanoyl groups from (R)-3-hydroxybutanoyl-CoA molecules and produces PHB and CoASH. Synthesized PHB is degraded by PHADP to form (R)-3-(...
The conversion of all quinolone compounds possessing a free carboxyl group, but not a free amino group, is carried out by using an excess of thionyl chloride as the reactive agent by the procedure according to Shriner, et al, The Systematic Identification of Organic Compounds, John Wiley, 1948...
(see Data Records). Additional criteria could be used to reduce either the solvent removal stability or thermal decomposition datasets. For example, multiple refinements of a MOF could have been carried out by multiple groups with distinct geometric properties or labels leading to either distinct ref...
In series I and II, one phenolic -OH group is esterified by 4-n-alkoxybenzoyl groups; in series III and IV both the phenolic -OH groups are esterified by 4-n-alkoxybenzoyl groups. All the homologues of series III and IV exhibit low melting smectic C phases. Monoesters of series I ...
