Ruthenium complexes of sterically-hindered pentaarylcyclopentadienyl ligands

The synthesis of ruthenium complexes incorporating an overcrowded pentaarylcyclopentadienyl ligand has been investigated, and higher efficiency has been reached using chlorine-functionalised precursors when compared with their brominated counterparts. A new methodology for the preparation of chlorocyclopentadienes has been developed which is well adapted for highly sterically hindered compounds and works with either electron rich or poor systems.

Directed synthesis of symmetric and dissymmetric molecular motors built around a ruthenium cyclopentadienyl tris(indazolyl)borate complex

This article focuses on the synthesis of a family of rotary molecular motors based on a penta-substituted cyclopentadienyl tris(indazolyl)borate ruthenium(II) complex. In order to demonstrate a movement of rotation in this family of molecular motors, diss

Tetraphenylcyclopentadiene and (4-tert-Butylphenyl)tetraphenylcyclopentadiene: Synthesis and Characterization of their Alkali-Metal Salts and Metallocenes of Germanium, Tin, and Lead

Tetraphenylcyclopentadiene (1) and (4-tert-butylphenyl)tetraphenylcyclopentadiene (11), their alkali-metal salts (2-4 and 12, 13, respectively)and their air-stable metallocenes of germanium (5, 15), tin (6, 16) and lead (7, 17) were synthesized and characterized by IR, Raman, 1H-NMR, 13C-NMR, and mass spectta as well as by X-ray powder diagrams.Comparative 13C-NMR studies including tetraphenylcyclopentadienyl bromide (8), (4-tert-butylphenyl)tetraphenylcyclopentadienol (9), and (4-tert-butylphenyl)tetraphenylcyclopentadienyl bromide (10) prove a delocalisation of the negative charge from the C5 ring into the nonparallel phenyl ligands.
