Abstract
cis‐(S) (+)‐2‐phenylvinyl alkyl ethers having as alkyl groups 1‐methylpropyl (I), 2‐methylbutyl (II), and 3‐methylpentyl (III) were synthesized by condensation of phenylacetylene with the corresponding sodium alcoholates. Polymerization of monomers was performed cationically with BF3 · Et2O or SnCl4 in toluene or CH2Cl2. Specific rotations of polymers were compared with those of low molecular weight model compounds prepared by hydrogenation of monomers, and it was concluded that the difference in the rotation of poly I and model compound ([α]D 19.3° and 5.68°, respectively) and poly II and model compound ([α]D 11.4° and 3.00°, respectively) can be attributed to the asymmetric induction at carbon atoms of the principal polymer chain.Keywords
