The parent phosphole and phospholyl anion as well as some C-substituted derivatives have been characterized by 1H and 13C NMR spectroscopy for the first time ; the two most noteworthy features are the absence of ³J(H-P-C-H) couplings for the phospholes and the huge ¹J(C-P) couplings for the phospholyl anions.
