Abstract N-Propargylbenzamides 1–7 were polymerized with (nbd) Rh+[η 6-C 6 H 5 B−(C 6 H 5) 3] to afford polymers with moderate molecular weights (M n= 26 000–51 000) in good yields. The 1 H NMR spectra demonstrated that the polymers have fairly stereoregular structures (81–88% cis). The optically active polymers, poly (1) and poly (2), were proven by their intense CD signals and large optical rotations to adopt a stable helical conformation ...
