Bromoniumsalts [(RF)2Br]Y with perfluorinated groups RFC6F5, CF3CFCF, C2F5CFCF, and CF3C≡C were isolated from reactions of BrF3 with RFBF2 in weakly coordinating solvents (wcs) like CF3CH2CHF2 (PFP) or CF3CH2CF2CH3 (PFB) in 30–90% yields. C6F5BF2 formed independent of the stoichiometry only [(C6F5)2Br][BF4]. 1:2 reactions of BrF3 and silanes C6F5SiY3 (Y = F, Me) ended with different products – C6F5BrF2

3-dimethylpentane (X), and perfluoro-3,4- dimethylhexane (III). Pyrolysis of IV in the presence of bromine gave (VI) and 3-bromo-3-trifluoromethyl-decafluoropentane (XI): with toluene, pyrolysis gare VlI and 3H-3-trifluoromethyldecafluoropentane (XII). Pyrolysis of II at 500° over glass gave perfluoro-1,2,3-trimethylcyclobutene (XIII) and perfluoro-2,3-dimethylpenta-1,3(E)- and (Z)-diene (XIV) and (XV) respectively
