Technology Process of Ethyldibromoborane

There total 15 articles about Ethyldibromoborane 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: 96.0%

triethylaluminum (97-93-8) + boron tribromide (10294-33-4) → ethyl-dibromo-borane (17933-10-7)

Guidance literature:

dropping slowly Al(C2H5)3 to BBr3 while stirring; temp. of the mixt. increases to 70°C; distn.;

Reference yield: 86.0%

tetraethyltin (597-64-8) + boron tribromide (10294-33-4) → ethyl-dibromo-borane (17933-10-7)

Guidance literature:

at -35°C with 2 mole BBr3;

Reference yield: 67.0%

aluminum bromide + triethylboroxine (3043-60-5) → 2,2,8,8,13-pentabromo-4,6,10,12-tetraethyl-1,3,5,7,9,11-hexaoxa-4,6,10,12-tetrabora-2,8,13-trialuminatetracyclo{7.3.1.0(3,13)0(7,13)}tridecane + ethyl-dibromo-borane (17933-10-7)

Guidance literature:

In hexane; boroxine was added under Ar to an agitated suspension of (AlBr3)2 in hexane;; dibromethylborane in hexane was filtered off from the crude prod., the latter was dried in vac. and recrystd. from hexane; elem. anal.;;

upstream raw materials:

triethylboroxine

tetraethyltin

ethene

hydrogen

Downstream raw materials:

1,2-diphenyl-3-ethyl-1,2-closo-dodecacarborane
