Technology Process of 1,2-diphenyl-1,2-disila-closo-dodecaborane⁽¹²⁾

There total 1 articles about 1,2-diphenyl-1,2-disila-closo-dodecaborane⁽¹²⁾ 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: 14.0%

N,N,N',N'-tetramethyl-1-phenylsilanediamine + nido-decaborane (17702-41-9) → 6,9-(Me2NH)2B10H12 (128270-50-8) + 1,2-diphenyl-1,2-disila-closo-dodecaborane(12) (148160-63-8)

Guidance literature:

In toluene; stirring and heating of a mixt. of the B- and the Si-compd. in toluene at 100-110°C for ca 48 h under N2; cooling to room temp. and filtn. gives the aminoborane (identification by NMR), the filtrate is concd. to ca one-third of its vol., pptn. on storing at 3°C overnight, further steps of concg. and cooling, recrystn. (exclusion of air) from toluene;
