INDEX phenylacetylene

WOCI4 is combined with Ph Sn (ratio WOCI4 Plx Sn = 1 2) in 1,4-dioxane/benzene to afford poly(phenylacetylene) efficiently, whose reaches 1.1 x 10 ([77] 1.23 dL g ) and whose m-content is 7i% High polymer yields can be achieved even in the case of a high monomer/catalyst ratio, 1260. The viscosity index, a, of poly(phenylacetylene) formed by this catalyst was determined to be 0.61, indicating a sufficiently flexible chain.

Recent examples that have utilized the hydrosilylation reaction to prepare very imique organosiloxanes are shown in equations 4 and 5. Equation 4 depicts the hydrosilylation of phenylacetylene to provide beta-vinyl silicones (84,85) and is a convenient route to high refractive index silicones.
