There total 3 articles about BORANE-4-ETHYLMORPHOLINE COMPLEX 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: 99.0%

N-ethylmorpholine; (100-74-3) + sodium tetrahydroborate (16940-66-2) → N-ethylmorpholine-4-borane (88996-22-9)

Guidance literature:

With carbon dioxide; In tetrahydrofuran; at 20 ℃; for 1h;

DOI:10.1039/d1dt03495b

Reference yield:

N-ethylmorpholine; (100-74-3) + diborane (19287-45-7) → N-ethylmorpholine-4-borane (88996-22-9)

Guidance literature:

In neat (no solvent); addn. of diborane to amine at liquid N2 temp., keeping at -111°C, -78°C and 0°C consecutively, stirring at 0°C for 4-6 h (vacuum line); cooling to -78°C, removal of B2H6 by distn.;

Reference yield:

N-ethylmorpholine; (100-74-3) + borane tetrahydrofuran → N-ethylmorpholine-4-borane (88996-22-9)
