Technology Process of bromodimethylaminocyclohexylphosphine(pentacarbonyl)chromium⁽⁰⁾

There total 2 articles about bromodimethylaminocyclohexylphosphine(pentacarbonyl)chromium⁽⁰⁾ 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: 71.0%

bis(dimethylamino)cyclohexylphosphine(pentacarbonyl)chromium(0) (126306-16-9) → bromodimethylaminocyclohexylphosphine(pentacarbonyl)chromium(0) (126306-28-3) + dimethylamine hydrobromide (6912-12-5)

Guidance literature:

With hydrogen bromide; In pentane; Under stirring a strong stream of hydrogenhalogenide is bubbled for 10 min through the cooled (0°C) soln. of phosphine complex (inert atmosphere).; Solvent is evapd. at room temp. in vac., residue is digested with pentane, dialkylamminhydrohalogenide is filtered off, filtrate is dried to dryness in vac., recrystn. from pentane (-78°C), elem. anal.;
