Two poly(trimethylsilyldiphenylacetylene) membranes containing different contents of fluorine-containing groups were prepared by direct perfluorodecylation of poly(trimethylsilyldiphenylacetylene) (poly 1) in the membrane state using different ratios of (perfluorodecyl)phenyliodonium triflates to the phenyl groups in the polymer. The resulting perfluorodecylated poly(trimethylsilyldiphenylacetylene)...
We have examined the role of the chiral amine cocatalyst in the recently discovered helix-sense-selective polymerization of a phenylacetylene using a catalytic system consisting of an achiral rhodium complex ([Rh(norbornadiene)Cl] 2 ) as the catalyst and a chiral amine as the cocatalyst. Several chiral amines were effective for the polymerization reaction and their effectiveness depended on...
