रुथेनियम इसके अंग्रेजी अर्थ का उदाहरण

The guest is a 16 electron and thus very reactive ruthenium metallocene (an organometallic catalyst) with a cyclopentadienyl ligand (red) and a 1,3,7-octatriene ligand (blue).

The ruthenium compound decomposes in water within minutes but encapsulated it survives in water for weeks.

Quenching is made use of in optode sensors; for instance the quenching effect of oxygen on certain ruthenium complexes allows the measurement of oxygen saturation in solution.

Another popular metal used in dihydroxylation is ruthenium.

Although it is highly oxidative, ruthenium has been used because of its short reaction time and its cost-effectiveness.

Typically, the ruthenium tetroxide is created in situ from ruthenium trichloride, and a secondary oxidant NaIO4 is used to regenerate the catalyst.

Similar to ruthenium, the oxidation potential of manganese is high, leading to over-oxidation of substrates.

Products introduced in 1981 Dicarbonyltris(triphenylphosphine)ruthenium(0) or Roper's complex is a ruthenium metal carbonyl.

In it, two carbon monoxide ligands and three triphenylphosphine ligands are coordinated to a central ruthenium(0) center.

In 1993, Grubbs and others not only published a report on carbocycle synthesis using a molybdenum catalyst, but also detailed the initial use of a novel ruthenium carbene complex for metathesis reactions, which later became a popular catalyst due to its extraordinary utility.

The ruthenium catalysts are not sensitive to air and moisture, unlike the molybdenum catalysts.

The ruthenium catalysts, known better as the Grubbs Catalysts, as well as molybdenum catalysts, or Schrock’s Catalysts, are still used today for many metathesis reactions, including RCM.

As a general trend, ruthenium NHC (N-heterocyclic carbene) catalysts favor E selectivity to form the trans isomer.
