Abstract
A diglyme solution of Na[cyclo-P5] (1) reacts with alkynes and the isolobal nitriles and phosphaalkynes to afford the otherwise elusive (aza)phospholide anions 2a-c, 4a,b, and 6. The reaction of Na[cyclo-P5] with alkynes and nitriles was studied by means of DFT methods, which suggest a concerted mechanism for the formation of 2a and 4b. The anions 2a-c, 4a,b, and 6 coordinate in an η5-fashion towards Fe(II) to give the sandwich (aza)phosphametallocenes 3a-c, 5a,b and 7 in moderate to good yields. The new compounds were characterized by means of multinuclear NMR spectroscopy, single crystal X-ray diffraction and cyclic voltammetry.
