Reaction Conditions

Reaction Steps

To a solution of 2-phenyl-1,3-dithiane (2.1 g, 10.69 mmol) in THF (5 mL) and cyclohexane (10 mL) was added n-BuLi (6.37 mL, 1.68 M in hexane) dropwise via a syringe at −78° C. The solution was stirred for an additional 3 hours at 0° C. The resulting 0.5 M 2-litho-2-phenyl-1,3-dithiane (abbreviated as PDT-Li) was used for anionic initiator for polymerizing butadiene and/or butadiene/styrene and stored in an inert atmosphere of nitrogen in a refrigerator.
