1,1-Bi(endo,exo,syn-pentacyclo[3.3.3.02,4.06,8.09,11]undecyl)[1,1-bi(trishomobarrelenyl)] (4) has been prepared as a 1:1 mixture of its meso- and d,l-diastereomers in six steps from trishomobarrelene 1 via the amine 5, the N,N-bis(trishomobarrelenyl)sulfam ...
Artificial neural networks represent a simple but efficient way to model and correct known errors existing between commonly used density functional computations and experimental data. The recently proposed X1 approach combines B3LYP energies with a neural- ...
Energies of alkanes computed with many popular and even newer density functionals are flawed by systematic errors, which become considerable with larger molecules. The same energies, however, are well described by post-Hartree-Fock methods. Similar DFT sho ...
The trigonal planar geometry of the nitrogen atom in commonly used phosphoramidite ligands is not in line with the traditional valence shell electron pair repulsion (VSEPR) model. In this work, the effects governing nitrogen configuration in several substi ...
