“…Complex 3 was obtained as dark brown crystals that were reasonably soluble in THF, CHCl 3 , and CH 2 Cl 2 . The 125 Te NMR spectrum (CD 2 Cl 2 ) of 3 shows a singlet at δ = –283.6 ppm, which resembles that of PhTeFe(CO)(PPh 3 )Cp ( δ = –275.5 ppm) . The 31 P chemical shift of 3 ( δ = 66.4 ppm) compares well with that of PhTeFe(CO)(PPh 3 )Cp ( δ = 73.9 ppm) …”

“…However, this is beyond the scope of this study. The Te–Fe bond length of 3 [2.524(1) Å] is considerably smaller than those of CpMn(CO) 2 PhTeFe(PPh 3 )Cp [2.600(1) Å] and PhTeFe(CO) 2 Cp [2.617(1) Å] and even more significantly smaller than the sum of the covalent radii of the atoms (2.70 Å), which might be attributed to some Fe to Te back‐bonding (Table ) …”

The reduction of the previously known [(6‐Ph2P‐Ace‐5‐)Te]Cl with K‐selectride (K[sec‐Bu3BH]) provided the title compound (6‐Ph2P‐Ace‐5‐)2Te2 (1). The oxidation of 1 under aerobic conditions afforded the related (6‐Ph2P(O)‐Ace‐5‐)2Te2 (2). Alternatively, 2 was prepared by reduction of the previously known 6‐Ph2P(O)‐Ace‐5‐TeCl with K‐selectride. The reaction of 1 with [Cp(CO)2Fe]2 proceeded with cleavage of the Te–Te and Fe–Fe bonds with elimination of CO and gave rise to a racemic mixture of (6‐Ph2P‐Ace‐5‐)TeFe(CO)Cp (3), which contains pseudo‐tetrahedral Fe atoms in a chiral environment. Upon crystallization, the racemate most likely undergoes spontaneous resolution into a conglomerate of enantiopure crystals.
