The Ruthenostannylene Complex [Cp*(IXy)H2Ru‐Sn‐Trip]: Providing Access to Unusual Ru‐Sn Bonded Stanna‐imine, Stannene, and Ketenylstannyl Complexes

Abstract: Reactivity studies of the thermally stable ruthenostannylene complex [Cp*(IXy)(H)2RuSnTrip] (1; IXy=1,3‐bis(2,6‐dimethylphenyl)imidazol‐2‐ylidene; Cp*=η5‐C5Me5; Trip=2,4,6‐iPr3C6H2) with a variety of organic substrates are described. Complex 1 reacts with benzoin and an α,β‐unsaturated ketone to undergo [1+4] cycloaddition reactions and afford [Cp*(IXy)(H)2RuSn(κ2‐O,O‐OCPhCPhO)Trip] (2) and [Cp*(IXy)(H)2RuSn(κ2‐O,C‐OCPhCHCHPh)Trip] (3), respectively. The reaction of 1 with ethyl diazoacetate resulted in a ti… Show more

“…previously reported the stannylene complex [Cp*( i Pr 3 P)HOs=SnH(trip)], featuring a hydridostannylene SnH(trip) coordination. They observed the 1 H NMR signal at 19.4 ppm and the 119 Sn NMR signal at 786 ppm ( 1 J Sn−H 775 Hz) . Diorganostannylenes and disilylated stannylenes coordinated at metallocene fragments also exhibit signals at low field in the 119 Sn NMR (Figure : B 1677 ppm; E Ti 1635, Zr 1263, Hf 1080; F Hf 1785, Ti 2172 ppm) …”

“…Sie diskutierten ein Gleichgewicht des Hydridtransfers zwischen Hydrido‐Metallostannylen (HM‐Sn‐R) und Hydridostannylen (M=SnHR), wobei für Zinn die Hydrido‐Metallostannylene energetisch bevorzugt sind [20a] . Beispiele für schwere Gruppe‐14‐Element Metall‐Dihydrid‐Komplexe wie [(Ph 3 P) 2 RhH 2 EAr*] (E=Sn 3 ; E=Pb 7 ) sind in der Literatur für folgende Elementkombinationen bekannt: Ge‐Ru, [20e,h] Mo, [20i] W, [4d] Rh; [14] Sn‐Os, [20g] Ru [20a,b] Hf, [20f] Rh; [14] Pb‐Ru [20a] …”
