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 C6F5XMR3, where X O or S,M Si,Ge,Sn, or Pb, and R Ch3 or C6H5 and of the type C6H5NHR where R BC6H52,CH3,H,SiCH33. Estimates of p to d pi bonding between group IV elements and oxygen, sulfur, and nitrogen are given. The influence of a sigma-bond polarity upon back donation by halogens is considered. Author
