26. 3 in a nitroge-containing glovebox. After the suspension was stirred overnight at room temperature, a thick mixture formed. Evaporation of the hexanes leaves an elastomer. The elastomer was quenched with 0.1 % BHT in 2-propanol and 1 mL of 5% hydrochloric acid.
27. 3 and then isoprene (3 mL, 30 mmol) were added via syringe. After the suspension was stirred overnight at room temperature, a thick mixture formed. Evaporation of the hexanes leaves an elastomer. The polymer was isolated as described in ref 25.
