Synthese und Komplexchemie funktionalisierter Tripod‐Liganden RC(CH2PPh2)3

Synthesis and Complex Chemistry of Functionalised Tripod Ligands RC(CH2PPh2)3Malonic ester 1 is alkylated and converted into the triols RC(CH2OH)3 (5). These are easily converted into the corresponding functionalised tripodal ligands RC(CH2PPh2)3 (7) with R  Bzl (a), n‐C12H25 (b), (CH3)2CH(CH2)2 (c). Crystals suitable for X‐ray crystallography have been obtained of the ligand 7a. In addition, the tripod ligands 7a and 7c have been further characterized by the syntheses and X‐ray analyses of the nickel complex [(7a)NiCl] (8a), the iron complex [(7c)Fe(NCCH3)3](BF4)2 [9 · (BF4)2], and the cobalt complex [(7c)Co{O(O)CCH3}](BPh4) (10 · BF4).
