Tungsten Pentacarbonyl-N-Pentylisonitrile丨CAS 347145-09-9

CAS: 347145-09-9
Chemical Formula/Abbreviation: W(CO)5CN(CH2)4CH3

Tungsten Pentacarbonyl-N-Pentylisonitrile is a typical zero-valent tungsten carbonyl-isonitrile complex. This compound consists of five carbonyl ligands and one N-pentylisonitrile ligand, combining the stability of tungsten carbonyls with the strong σ-donating properties of the isonitrile ligand. Due to its well-defined coordination structure and tunable reactivity, it is often used as an important research-grade precursor in organometallic synthesis, coordination chemistry, and catalytic mechanism studies.

Precautions

  1. Tungsten pentacarbonyl-N-pentylisonitrile is sensitive to air and moisture; it is recommended to handle it in a glove box or under an inert atmosphere.

  2. Prolonged exposure to light may cause slow decomposition, affecting the integrity of the carbonyl ligands; therefore, strong light exposure should be avoided.

  3. CO may be released during heating or decomposition; therefore, the procedure should be performed in a well-ventilated laboratory environment.

  4. If the product accidentally comes into contact with skin or eyes, rinse immediately with plenty of water.  If the situation is serious, seek medical attention promptly.

  5. The operating procedure strictly follows the product's MSDS manual.
