NN'-Diarylacetamidines R'NHC(Me)NR', NN'-diarylbenzamidines R'NHC(Ph)NR', and NN'-diarylformamidines R'NHC(H)NR' (R'=Ph or C6H4Me-p) react thermally or photolytically with and/or 2> (X= Cl or Br) to afford air-stable, white complexes, X>, containing monodentate amidine ligands.The corresponding lithioamidines (R= Me or Ph) gave white carbamoyl complexes >, which are converted thermally to NN'-bidentate > and ortho-metallated > (R''=H or Me).The latter complexes are also formed by further reaction of the carbamoyl complexes with the corresponding amidine.The carbamoyl complexes react with PPh3 to form >.Lithioamidines in excess react with (X= Cl or Br) complexes to give adducts formulated as Li(1+)2>(1-).The new complexes are characterised, and structural data obtained by i.r. and n.m.r. spectroscopy.
