“…Characterisation data of the second component were coincident with those reported for ferrocenecarboxaldehyde, 18 which may form through hydrolysis of the Schiff base. This finding is similar to those reported for the cycloplatination of the diimine derived from the condensation of benzaldehyde and (1R,2R)diaminocyclohexane 9a or for the cyclopalladation of: C 6 H 5 -CH=N-(CH 2 ) 2 -SEt, 19 which also lead to small amounts of benzaldehyde. 9a,19 Characterisation data of the minor component (%10 mg, 2b, vide infra) suggest that it is an isomeric form of 2, in which the ligand has the E (anti) conformation.…”

The study of the reactivity of [(Z 5 -C 5 H 5 )Fe{(Z 5 -C 5 H 4 )-CH=N-(CH 2 ) 3 -NMe 2 }] (1) with cis-[PtCl 2 (dmso) 2 ] is reported. These studies have allowed the isolation and characterisation of two isomeric forms of cis-[Pt{(Z 5 -C 5 H 5 )Fe[(Z 5 -C 5 H 4 )-CH=N-(CH 2 ) 3 -NMe 2 ])}Cl 2 ] (2a and 2b), which differ in the conformation of the ligand [syn-(Z) in 2a and anti-(E) in 2b], and the first platinacycle containing a terdentate [C(sp 2 , ferrocene),N,N 0 ] À ligand: [Pt{[(Z 5 -C 5 H 3 )-CH=N-(CH 2 ) 3 -NMe 2 ]Fe(Z 5 -C 5 H 5 )}Cl] (3). The relative importance of the factors governing the formation of 3 is discussed. The X-ray crystal structures of 2a and 3 are described and confirm the mode of binding of the ligand to the platinum(II). The study of the reactivity of 3 with PPh 3 or CH 3 I is also reported.

“…The FTIR spectra of 1 and 2 are characteristic and showed >C═N stretching vibrations at 1645 and 1650 cm −1 , respectively, whereas these bands were absent in the IR spectra of 3 and 4 . The Te−C (alkyl) stretching vibrations were observed in the IR spectra at 504–520 cm −1 , whereas those of Te−C(aryl) appear at 282–292 cm −1 , which are comparable with the literature values .…”

The condensation of 3‐(4‐methoxyphenyltelluro)propylamine and bis(3‐aminopropyl) telluride with 2‐hydroxyacetophenone formed two Schiff's bases 2‐[1‐(3‐(4‐methoxyphenyltellanyl)propylimino)ethyl]phenol (1) and Bis 2‐[1‐(3‐iminopropyltellanyl)ethyl]phenol (2), respectively. The reduction of 1 and 2 gave compounds 2‐[1‐(3‐(4‐methoxyphenyltellanyl)propylamino)ethyl]phenol (3) and Bis 2‐[1‐(3‐aminopropyltellanyl)ethyl]phenol (4), respectively. These four new organotellurium compounds (1–4) were characterized by 1H and 13C NMR and FTIR spectroscopies and atomic absorption spectrophotometer (AAS) (Te). The conductance and molecular weights and composition by elemental analysis (C, H, and N) of 1 and 2 were determined. The compound 4 was also characterized by 13C DEPT‐135 NMR spectrum. The compounds 1 and 3 are unsymmetrical, and 2 and 4 are symmetrical type of telluroethers. The single crystals of 1 and 2 were grown, and their molecular structures were determined by single crystal X‐Ray diffraction. The ArC–Te bond length in 1 was found 2.117(7) Å. The RC–Te bond length in 1 is 2.141(5) Å and in 2 is 2.146(5) and 2.150(6) Å. The >C═N bond lengths in 1 and 2 were between 1.278(6) and 1.295(6) Å. There exists intramolecular O−H…N hydrogen bonding [between 1.758(4) and 1.792(4) Å] in 1 and 2. In compound 2, these nonbonded interactions result in the formation of a R22 (34) dimeric ring. CH…O [2.505(4)–2.516(3) Å] in 1 and 2 and CH…π [2.61(5) and 2.89(4) Å] secondary interactions are also present in 2.
