    Description / Table of Contents: (Allyl)(η5-cyclopentadienyl)(triorganylphosphan)ruthenium Complexes; Preparation and RearrangementsThe 2-alkenylmagnesium halides 2-5 react with (η5-Cyclopentadienyl)bis(triorganylphosphane)ruthenium chloride 1 in Toluene/ether (ca. 10:1) to yield the corresponding (η1-2-alkenyl)ruthenium complexes 6-12 which, on heating, rearrange into Cp(PR3)(η3-all)Ru 13 - 17. With the 2-methylallyl compound 7 the η1 → η3 rearrangement occurs according to a S1-, with the other complexes 6, 8 and 9 according to a S2-mechanism. Apart from the η → η3 rearrangement an allylic isomerization to 18 and 19 via a hydrogen shift is observed in the case of 16.
    Notes: Die 2-Alkenylmagnesiumhalogenide 2-5 reagieren mit (η5-Cyclopentadienyl)bis(triorganylphosphan)rutheniumchlorid 1 in Toluol/Ether (ca. 10:1) zu den entsprechenden (η1-2-Alkenyl)-rutheniumkomplexen 6 - 12, die sich beim Erhitzen in Cp(PR3)(η3-all)Ru 13 - 17 umlagern. Die η1 → η3-Umlagerung verläuft bei der 2-Methylallyl-Verbindung 7 nach einem S1-, bei den anderen Komplexen 6, 8 und 9 nach einem S2-analogen Mechanismus. Neben der η1 η η3-Umlagerung beobachtet man bei 16 eine unter Wasserstoffverschiebung verlaufende Isomerisierung des Allylsystems zu 18 und 19.
