Pentacovalent P and Sb compds., e.g. pentaphenyl-phosphoranes, phenyldi(biphenylylene)phosphoranes, and alkyl, phenyl, or mixed phenylalkylstiboranes, readily underwent nucleophilic ligand exchange when treated with alkyl or aryl lithium compds. The ligand ...
A compound, in metal-free or metal complex form of formula (1) to (3) in which R is hydrogen or C1-30 alkyl; X is hydrogen, halogen (preferably Cl or Br) or C1-30 alkyl. ...

Since the first facile synthesis of Ru(H2O)(6)(2) was published at the beginning of the eighties, several Ru-II aqueous inorganic and organometallic complexes were described, showing the increasing interest in this kind of compound due to potential ...
A set of Al2O3 samples were superplastically crept or stress-free annealed in identical conditions. Detailed quantitative microstructural evaluations of: grain sizes, shapes, orientations, coordination number and their distributions, were performed as well ...
