Synthesis and Crystal Structure of Iminophosphanes Containing Ligands with High π‐Donor Ability Reaction of the lithiated ketimines LiN=CR 2 (R 2 = tBu 2 , fluorenyl) 1a,b with the chloro(arylimino)phosphanes Cl–P=N–Ar (AR = 2,4,6‐tBu 3 C 6 H 2 ) 2 affords the heterobutadienes R 2 C=N–P=NAr 3a,b . The X‐ray structure determination of 3a,b reveals an unusually short P–N single bond both cis and trans arrangements of the NPN skeleton.
