Reactionmechanisms for the synthesis of indenamines, indenols,and isoquinolinium salts through cobalt- and rhodium-catalysis wereinvestigated using density functional theory calculations. We foundthat the valence charge of transition metals dramatically influencesthe reaction pathways. Catalytic reactions invo...
Said particles contain at least one oxidic compound of elements that are selected from the first to fifth main groups, the transition metals and/or the lanthanoids and have particulate prominences on their surface... G Carsten,W Herbert,S Werner - EP 被引量: 23发表: 2002年 The design of...
The critical conditions for the reaction of particles of the transition metals titanium (Ti) and zirconium (Zr) dispersed during the detonation of long cylindrical explosive charges have been investigated experimentally. The charges consisted of packed beds of either spherical Ti particles or ...
(a–c) Specimen Elba or alkali-poor beryl shows a well-developed quadrupolar shape in the STMAS profile, with the shape of the central transition 1/2, green in (b), and the transition 3/2 red in (c). Two sites for Be atoms are resolved, BeI and BeII in (b). (d–f) Specimen...

It is shown that the oxidation state formalism provides a framework for the classification of families of compounds related by ligand substitution or redox processes, and can neither be replaced by nor deduced from net atomic charges.关键词: Transition metals Oxidation states Population analysis DFT ...
For example, the name for CaSO4 is calcium sulfate.Most of the transition metals and some main group metals can form two or more cations with different charges. Compounds of these metals with nonmetals are named with the same method as binary compounds, except the charge of the metal io...
