A series of sulfur chelated dormant ruthenium olefin metathesis catalysts is presented. The catalysts prepared were shown to possess the uncommon cis-dichloro arrangement and were mostly inactive at room temperature. By systematically modifying the size of the substituent groups at the chelating sulfur atom, catalyst activity at different temperatures was significantly affected; more bulky substituents fomented activity at lower temperatures. The catalysts were also shown to be stable in solution and retained their catalytic activity even after being exposed to air for two weeks.
By systematically modifying the substituent group bulkiness at the chelating sulfur atom, catalyst activity at different temperatures was fine tuned; larger substituents fomented activity at lower temperatures.Figure optionsDownload as PowerPoint slide
