Technology Process of (benzonitrile)(pentacarbonyl)tungsten

There total 18 articles about (benzonitrile)(pentacarbonyl)tungsten which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 80.0%

pentacarbonyl(phenylthiobenzylidene)tungsten + S,S-Diphenylsulfilimine (36744-90-8) → (benzonitrile)(pentacarbonyl)tungsten (19705-90-9)

Guidance literature:

In diethyl ether; a soln. of an imine complex was treated with sulfilimine at room temp., after 5 min the mixt. was chromd. on SiO2 column at -10°C, eluent Et2O-hexane (1:1); identified by IR and mass spectra;

DOI:10.1021/om00151a028

Reference yield: 80.0%

n-butyllithium (109-72-8,29786-93-4) + (CO)5WNHC(OCH3)C6H5 (109011-18-9,109063-26-5) → (benzonitrile)(pentacarbonyl)tungsten (19705-90-9)

Guidance literature:

In diethyl ether; a soln. of an imine complex was treated with BuLi at - 20°C, after stirring for 30 min the yellow mixt. was filtered through SiO2, the solvent was evapd.; identified by IR and mass spectra;

DOI:10.1021/om00151a028

Reference yield: 62.7%

pentacarbonyl(ethylthiobenzylidene)tungsten + S,S-Diphenylsulfilimine (36744-90-8) → (benzonitrile)(pentacarbonyl)tungsten (19705-90-9) + (CO)5WNHC(SCH2CH3)C6H5 (109011-23-6,109063-29-8)

Guidance literature:

In diethyl ether; a soln. of a thiocarbene complex was treated with sulfilimine at room temp., after stirring for 5 min the mixt. was separated at SiO2 column at -10°C, eluent Et2O-hexane (1:1); isolated from second yellow fraction as an approx. 1:1 mixt. of E and Z isomers; identified by elem. anal., IR and NMR spectra;
