What is Trityl tetrakis(pentafluorophenyl)borate?

Chemical properties

Yellow to mustard colored powder

The Uses of Trityl tetrakis(pentafluorophenyl)borate

Used as a pharmaceutical intermediate.

Synthesis

trityl tetrakis(pentafluorophenyl)borate is prepared by mixing LiB(C6F5)4 and trityl chloride in hexane and refluxing overnight. It is prepared also by one-pot procedure starting from bromopentafluorobenzene.

Solubility in organics

soluble in CH2Cl2, MeOH, and acetone, but its yellow color disappears because these solvents coordinate to the trityl salt.
