Pyramidal InversionWiley - Tập 9 Số 6 - Trang 400-414 - 1970

AbstractPyramidal inversion is discussed from the point of view of recent theoretical and experimental investigations in an attempt to provide a unified description of this process. Quantum mechanical studies of pyramidal molecules indicate that the origin of the inversion barrier may be dependent on the degree of angular constraint. Effects due to the electronegat...... hiện toàn bộ

AbstractThe search for new metal‐catalyzed asymmetric reactions has provided some fascinating insights into the effects imposed on the metal catalysts by chiral ligands. A practical consequence is the discovery of ligand‐accelerated catalysis (LAC). Thus, an existing catalyzed process is improved by the addition of a specific ligand, which leads to a faster, “ligan...... hiện toàn bộ
