Abstract

1,8-Bis(dimethylphosphonito) naphthalene Nap[P(OMe)(2)](2) (Nap=naphthalene-1,8-diyl) and a complete series of its mono- and di-oxidized phosphonato counterparts Nap[P(E)(OMe)(2)](2) (E=O, S, Se, lone pair and all their permutations) were prepared and fully characterized by X-ray crystallography and multinuclear NMR, IR, Raman and MS. Molecular distortion due to non-bonded substituent interactions was studied as a function of the bulk of the phosphorus substituents. The least and most strained molecules in the series are Nap[P(OMe)(2)](2) and Nap[P(Se)(OMe)(2)](2) with non-bonding P...P distances of 2.91 and 3.79 Angstrom respectively.
