    Description / Table of Contents: Functionally Substituted Organotin Compounds. IV. Synthesis and Reactivity of (2-Di-organophosphinoethyl)triorganostannanesThe title compounds 1a-1g are synthesized by radical addition of triorganostannanes to vinyl diorganophosphines. Their methioiodides 4b-4e undergo by heating a heterolytic fragmentation. The halogenation of 1a-1g depends on the reaction conditions and give rise to fragmentation reactions or the formation of organophosphorus substituted tin halides 6a-6e. The reaction of alkali metals with 1a-1g in liquid ammonia leads to a splitting as well as of tin and phosphorus-carbon bonds depending on the substituents.
    Notes: Die Titelverbindungen 1a-1g werden durch radikalische Addition von Triorganostannanen an Vinyl-diorganophosphine synthetisiert. Ihre Methioiodide 4b-4e unterliegen beim Erhitzen einer heterolytischen Fragmentierung. Die Halogenierung von 1a-1g hängt von den Reaktionsbedingungen ab und führt entweder zu Fragmentierungsreaktionen oder zur Bildung der organophosphorsubstituierten Zinnhalogenide 6a-6e. Die Reaktion von Alkalimetallen mit 1a-1g in flüssigem Ammoniak hat in Abhängigkeit von den Substituenten sowohl die Spaltung von Zinn-als auch von Phosphor-Kohlenstoff-Bindungen zur Folge.
