Enantiomerically pure (1) and rucemic (2) methyl-N-( 1-phenylethyl)-2-azabicycld2.2.1 lhept-5-ene-3-carboxylate were found to undergo ring opening metathesis polymerization reactions employing molybdenum alkylidene initiators of the type Mo(CH-t-Bu)(NArXOR), (Ar = 2,6-C,Ha-i-Pr2; R = C(CH,),; C(CH,)
Abstraet--5,6-Bis(chloromethyl)bicyclo[2.2.1]hepta-2-ene undergoes ring opening metathesis polymerization to give poly{1,4-[2,3-bis(chloromethyl)-cyclopentylene] vinylene}. Initiation with MoCIs/MeaSn derived catalyst gives atactic polymer with predominantly trans vinylenes, whereas initiation with
## Abstract The title monomers 1 and 2 were polymerized by Ruβ, Irβ, Moβ, Wβ and Reβbased metathesis catalysts to yield polymers with __cis__ contents ranging from 10% to at least 90% for 1 and 23β60% for 2. Assignments of the ^13^C NMR spectra were made. No significant headβtail bias was observed
