Ring-tilted metallocenophanes, strained

Ring-Opening Polymerization of Strained, Ring-Tilted Metallocenophanes New Route to Polymers Based on Transition Metals... [Pg.442]

The first examples of the use of ROP of strained metallocenophanes to prepare high molecular weight polymetallocenes (Mn>10 ) involved silicon-bridged [Ijferrocenophane monomers 3.21 [61]. Specifically, polyferrocenylsilanes (PFSs) 3.22 (R,R = Me or Ph) were prepared by the thermal ROP of strained, ring-tilted silicon-bridged [l]ferrocenophanes 3.21 (R,R = Me or Ph) in the melt, at 130-... [Pg.82]

To prepare [2]metallocenophanes that are even more strained than [2]ferrocenophanes 30, species with a larger ruthenium atom in the place of iron have been synthesized (81). Such [2]ruthocenophanes would be expected to possess much greater ring-tilt angles moreover, because ruthenocene is known to possess significantly different electrical properties compared to ferrocene, modified polymer properties would be anticipated (57). [Pg.158]
