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:
- Guidance literature:
-
With
lithium aluminium tetrahydride;
In
tetrahydrofuran;
LiAlH4 is added to THF under nitrogen, to this soln. is added dropwise a soln. of dodecaborane-compd. in THF over a 2 h period, the mixt. is stirred for 12 h at room temp.; THF is evaporated, the residue cooled in ice, diluted with water followed by aq. NaOH, extracted with ether, the extract is washed with water and concentrated, the residue is chromatographed on silica and the oil solidified after 24 h at 4°C;
- Guidance literature:
-
With
pyridine;
In
benzene;
pyridine is added to a cooled soln. of PBr3 in dry benzene, a soln. of dodecaborane-compd. in dry benzene is added to the cooled mixt. at a rate designed to keep the temp. under 0°C, stirring for a further 1 h, warming to room temp.; the mixt. is stored at room temp. for 48 h after which the solvent is evaporated, the residue is dissolved in CH2Cl2, the soln. is washed with water and brine, evaporated and chromatographed on silica, recrystn. from aq. EtOH;
