摘要

The catalytic coupling of cyclopentene oxide with carbon disulfide has been investigated utilizing (salen) CrCl in the presence of added onium salts. Both polymeric and cyclic materials were produced, with oxygen/sulfur atom scrambling observed in both instances. This atom redistribution process was found to require (salen) CrCl and excess epoxide, though an increase in the rate of atom scrambling was noted upon the addition of the ...
