Photofragmentation voltammetry studies of the aminocarbene complexes [(η5-C5H5)Fe(CO)(L){
C(NHR1)(R2)}]BF4[L = PPh3, P(p-Tol)3; R1= Me, CH2Ph; R2= Me, Bu]
Abstract
The synthesis of the complexes [(η5-C5H5)Fe(CO)(L){C(NHR1)(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.
