Twelve common density functional methods and seven basis sets for geometry optimization were evaluated on the accuracy of 1H/13C NMR chemical shift calculations for biaryls. For these functionals, 1H shifts calculations for gas phase optimized geomet

Due to its effect on the operation time of wind turbines, rotor imbalances of a wind turbine have to be detected early enough. We present a method that determines inhomogeneous mass distributions of the rotor as well as deviations in the pitch angles

Traceless point-to-axial chirality exchange is a growing method for the preparation of axially chiral biaryls/heterobiaryls. During the exchange, stereogenic centers are destroyed and a chiral axis is simultaneously created. Highly functionalized ena

The calculations of 1H and 13C NMR chemical shifts were performed on three 5–5 lignin dimers, prominent substructures in softwood lignins, to compare with experimental data. Initially, 10 DFT functionals (B3LYP, B3PW91, BPV86, CAM-B3LYP, HCTH, HSEH

The α-alkylation of ketones and their derivatives by the addition of their corresponding enolates to alkyl halides is a fundamental synthetic transformation, but its utility is limited because the key bond-forming step proceeds in a bimolecular nucl

We derive explicit formulas for the exact integration of the product of B-spline basis functions, which are further used to calculate the stiffness matrix of B-spline surfaces. Based on the fact that the B-spline product can be expressed as a linear

α-Substituted-β-hydroxy ketones are valuable intermediates, but their preparation by alkylation of enolates is difficult with hindered electrophiles. Now, a direct method for preparing α-substituted-β-hydroxy ketones — including those having α
