The He(1) photoelectron spectra of 1,1,3,3-tetrakis(dimethyl-calculations carried out by using the MNDO procedure. The amino)-lh5,3h5-diphosphabenzene (1 a), 1,1,3,3,5,5-hexakis(di-investigations reveal that the first bands correspond to n-MOs methylamino)-lh5,3h5,5h5-triphosphabenzene (2a), 4-tert-bu-which are mainly localized on the C atoms of the six-memt y l -1 , 1 , 3 , 3 -t e t r a k i s ( d i m e t h y l a m i n o ) -l h 5 , e n -bered ring. The MO calculations predict a strong negative net zene (3a), and the substitution products 4a and 5a of l a have charge for the ring carbon atoms adjacent to the P atoms and been recorded. The assignment of the PE spectra is based on strong positive net charges for the P atoms. a comparison of the PE spectra of related species with the MO ') Dedicated to Professor Alexandru T.
