AbstractSeveral ways to functionalize hydroxy-tripod-ligands (HOCH2C(CH2PR2)3) by activation with electrophiles are presented. The use of carboxylic halides and anhydrides is shown to be generally successful for esterification reactions in a one-pot synthesis starting from the oxetanes O(CH2)2C(CH2PR2)2. Facial coordinaton of the related esters towards iron(II) and molybdenum(O) can be achieved depending on the nature of the phosphane donor groups. If methyliodide or trimethylsilylchloride are used as electrophiles in order to functionalize the hydroxy group in HOCH2C(CH2PR2)3, it is necessary to proctect the phosphane groups by formation of the tris-borane adduct. All new compounds have been fully characterized by the usual analytical techniques as well as by X-ray analyses on selected examples.
