ABSTRACT We synthesized cyclic tetrathioesters containing thioester moieties at the o- position (o-CTE) and m-position (m-CTE) of an aromatic skeleton. The reaction of phenoxy propylenesulfide (PPS) with o-CTE and m-CTE was examined using tetrabutylammonium chloride as a catalyst in 1-methyl-2-pyrrolidinone, yielding the corresponding cyclic polysulfides poly [o-CTE (PPS) n] with M n's= 37,000–54,000 at 34–61% yields and poly [ ...
