There total 2 articles about (triphenylphosphonio)methanide-3,5-dimethylborabenzene 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: 61.0%

1-chloro-3,5-dimethyl-2-(trimethylsilyl)-1,2-dihydroborinine (300362-35-0) + Methylenetriphenylphosphorane (19493-09-5) → (triphenylphosphonio)methanide-3,5-dimethylborabenzene (431988-17-9)

Guidance literature:

In diethyl ether; byproducts: (Ph3PCH2SiMe3)Cl; under N2, conventional Schlenk techniques; soln. of Ph3PCH2 in ether added dropwise to B compd. (molar ratio 2:1) in ether; stirred at ambient temp. for 2 h; filtered; ppt. washed with ether; suspended in toluene; stirred at 100°C for 10 min; solid removed by fast filtration of hot suspn.; washed with toluene; combined filtrates concd.; crystd. at 4°C; elem.anal.;
