Photofragmentation voltammetry studies of the aminocarbene complexes [(η5-C5H5)Fe(CO)(L){=C(NHR 1)(R2)}]BF4 [L = PPh3, P(p-Tol)3; R1 = Me, CH2Ph; R2 = Me, Bu]

The synthesis of the complexes [(η5-C5H5)Fe(CO)(L){=C(NHR 1)(R2)}]BF4 [L = PPh3, P(p-Tol)3; R1 = Me, CH2Ph; R2 = Me, Bu] is described. Photofragmentation voltammetry is used to demonstrate that the primary photoprocess is loss of the phosphine ligand in all four carbene complexes. A common intermediate is observed when the analogous aminocarbenes are studied.
