- W2115587191 abstract "An improved protocol for the selective dilithiation of [V(η5-C5H5)(η7-C7H7)] has been developed, which afforded [V(η5-C5H4Li)(η7-C7H6Li)]⋅PMDTA (5; PMDTA=N,N,N′,N′′,N′′-pentamethyldiethylenetriamine) in almost quantitative yield (98 %). In the solid state, the species features a dimeric structure with two terminal and two bridging lithium atoms, with the latter connecting both sandwich subunits. Reaction with suitable Group 4 dihalide compounds enabled the isolation of highly strained silicon- and germanium-bridged [1]trovacenophanes 6 and 7. Similarly, reaction of 5 with Cl2Sn2tBu4 afforded the rather unstrained complex [V(η5-C5H4)(η7-C7H6)Sn2tBu4] (8), which together with 7 represent the first trovacenophanes to incorporate heavier analogues of silicon in the ansa-bridge. Ring-opening polymerization reactions of [V(η5-C5H4)(η7-C7H6)SiRR′] (2 a: R=R′=Me; 6: R=Me, R′=iPr) were performed by heating in a solution of toluene in the presence of the Karstedt catalyst, which resulted in the formation of the corresponding soluble poly(trovacenylsilanes) in yields of 41 and 33 %, respectively. As estimated by gel permeation chromatography (GPC), the macromolecules possess molecular weights of Mn=10 010 and 5580 g mol−1 with polydispersity indices of 2.31 and 1.64 for 9 and 10, respectively. ESR spectroscopic studies on 9 and 10 revealed only a single broad resonance in each case without any identifiable 51V hyperfine coupling." @default.
