Technology Process of (CH₃(CH₂)3)4N⁽¹⁺⁾*HBBr₃^(1-)=(CH₃(CH₂)3)4NHBBr₃

There total 3 articles about (CH₃(CH₂)3)4N⁽¹⁺⁾*HBBr₃^(1-)=(CH₃(CH₂)3)4NHBBr₃ 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: 94.0%

boron tribromide (10294-33-4) + tetrabutylammonium borohydride → (CH3(CH2)3)4N(1+)*HBBr3(1-)=(CH3(CH2)3)4NHBBr3 (76522-06-0) + diborane (19287-45-7)

Guidance literature:

In dichloromethane; BBr3 condensing under N2 at -196°C onto ammonium salt in CH2Cl2,warming to room temp., stirring for 2 h, cooling to -78°C, volatiles fractionating, diborane collecting at -196°C; identified by IR spectrum;
