 Title    Functionalized 1,2-Dioxetanes as Potentially Useful Biological and Chemotherapeutic Agents  
 Abstract    H ydroxym ethyl-substituted 1,2-dioxetanes (3) have been converted in reasonable yields (10—40%) into the carboxylate-substituted 1,2-dioxetanes (4) by means of the Brew ster—Ciotti or

 Title    Funktionalisierte tripod-Liganden mit Neopentan-Grundgerüst: Umsetzung von HOCH2C(CH2PR 2)3 mit Elektrophilen  
 Abstract    Several ways to functionalize hydroxy-rn'pod-ligands (H O C H 2C (C H 2PR2)3) by activation with electrophiles are presented. The use o f carboxylic halides and anhydrides is shown to be generally successful for esterification reactions in a one-pot synthesis starting from the oxetanes 0 (C H 2)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 H O CH 2C (CH 2PR2)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.
