Abstract : The pi interactions within molecules containing the pentafluorophenyl group are examined using the coupling constant-chemical shift relationship as proposed in the preceding paper. The following series, selected from the 73 pentafluorophenyl compounds studied, are discussed: pentafluorophenylphosphines and some of their complexes including metal carbonyl derivates: compounds of the type

Novel processes for preparing poly(pentafluorosulfanyl)aromatic compounds are disclosed. Processes include reacting an aryl sulfur compound with a halogen and a fluoro salt to form a poly(halotetrafluorosulfanyl)aromatic compound. The poly(halotetrafluorosulfanyl)aromatic compound is reacted with a fluoride source to form a target poly(pentafluorosulfanyl)aromatic compound.
A method for chemically modifying a peptide, derivative or analogue thereof is described. The method comprises contacting a peptide, derivative or analogue thereof with a fluoro-heteroaromatic compound to activate the peptide, derivative or analogue thereof. The activated peptide, derivative or analogue thereof is then contacted with a nucleophile or base to create a chemically modified peptide, derivative or analogue thereof.
