Thermotropic Liquid-Crystalline and Light-Emitting Properties of Bis(4-aalkoxyphenyl) Viologen Bis(triflimide) Salts

Molecules, 2020
A series of bis(4-alkoxyphenyl) viologen bis(triflimide) salts with alkoxy chains of different lengths were synthesized by the metathesis reaction of respective bis(4-alkoxyphenyl) viologen dichloride salts, which were in turn prepared from the reaction ...

Ruthenium Olefin Metathesis Catalysts Bearing Carbohydrate-Based N-Heterocyclic Carbenes [PDF]

, 2010
Ru-based olefin metathesis catalysts containing carbohydrate-derived NHCs from glucose and galactose were synthesized and characterized by NMR spectroscopy. 2D-NMR spectroscopy revealed the presence of Ru−C (benzylidene) rotamers at room temperature, and

Transition metal complexes of the weakly coordinating carborane anion [CB11H12]−: the first isolation and structural characterisation of an intermediate in a silver salt metathesis reaction

Chemical Communications, 2000
Reaction between CpMo(CO)3I and Ag[CB11H12] eventually affords CpMo(CO)3(η1-CB11H12), via the dimeric compound [CpMo(CO)3I·Ag{CB11H12}] 2 which represents the first structurally characterised intermediate in a silver salt metathesis reaction.

Synthesis of 7,7,14,14-tetrachlorodinaphtho[1,8bc:1′,8′-fg][1,5]distannocine. Molecular structure of the di-water tetra-THF adduct

Main Group Metal Chemistry, 2013
The salt metathesis reaction of 1,8-dilithionaphthalene with tributyltin chloride provided 1,8-bis(tributyltin)naphthalene (1) in 41% yield. The transmetallation of 1 with tin tetrachloride gave rise to the formation of 7,7,14,14-tetrachlorodinaphtho[1 ...
