Terao, Kimitada published the artcileA new highly sterically demanding silyl (TEDAMS) group. Synthesis by multiple substitution of tris(diphenylmethyl)silane with diarylcarbenium ions, Application of Bis(4-fluorophenyl)methane, the publication is Tetrahedron Letters (2010), 51(31), 4107-4109, database is CAplus.
A highly efficient electrochem. method for synthesis of halosilanes bearing bulky substituents was developed. Electrophilic multiple substitution on tris(diphenylmethyl)silane with diarylcarbenium ions afforded a highly sterically demanding hydrosilane, tris(extended diarylmethyl)silane (TEDAMS-H), which was converted to the corresponding bromosilane (TEDAMS-Br).
Tetrahedron Letters published new progress about 457-68-1. 457-68-1 belongs to catalysis-chemistry, auxiliary class Fluoride,Benzene, name is Bis(4-fluorophenyl)methane, and the molecular formula is C16H12O, Application of Bis(4-fluorophenyl)methane.
