摘要
The oligomerization stereochemistry of the products of equation 1 was studied by 1h and 13c NMR. The stereochem√istry of methylation and 2-vinylpyridine addition was found to be identical. With Li and Na as counterion both reactions lead to the formation of meso dyads so that the products are pre√dominantly isotactic. © 1979, Walter de Gruyter. All rights reserved.
