Access to 1,1′‐Bifunctional Phosphane Iron(0) Complexes via P–N Bond‐Forming Reactions and Selective P‐Functionalizations

Abstract: Reaction of Li/Cl phosphinidenoid Fe(CO) 4 complex 2 with ammonia and different amines R 1 ,R 2 NH yielded complexes 3-5 (3: R 1 = R 2 = H; 4a: R 1 = H, R 2 = Me; 4b: R 1 = H, R 2 = iPr; 4c: R 1 = H, R 2 = tBu; 4d: R 1 = H, R 2 = allyl; 4e: R 1 = H, R 2 = Ph; 5: R 1 = Me, R 2 = Me) having 1,1′-bifunctional phosphane ligands via formal N-H bond insertion of the phosphorus center. Studies on deprotonation enabled access to the first struc- [a]

“…The 31 P resonance signals of M-5b are 20 ppm downfield-shifted in comparison to 3b, in general, which is in accordance to previously observed M/N(H)R phosphinidenoid complexes [15][16][17]. In addition, the 1 J W,P coupling constant has a characteristically small value [12][13][14][15][16][17][18][19].…”

“…Two substituents at the nitrogen centre shift the resonance to the downfield region. The observed 1 J W,P and 1 J P,H coupling constants of 3a-f are of similar magnitude, as expected from related derivatives [12,13,[15][16][17].…”
