Synthesis and application of novel ruthenium catalysts for high temperature alkene metathesis

HIGHLIGHTS

• who: Tegene T. Tole and collaborators from the Four pyridinyl alcohols and four ruthenium-based precatalysts were successfully synthesizedThe pyridinyl alcohol, (, pyridinyl)-1-(4-methoxyphenyl)-1-phenyl-methanol, the two chloro-substituted and the methoxy-substituted pyridinyl alcoholato ruthenium precatalysts were also synthesized for the first time. The very good performance of the, chloro- and, methoxy-substituted pyridinyl alcoholato ligand containing ruthenium precatalysts, at high temperatures, makes them very good precatalysts for high temperature linear olefin metathesis reactions. The significant increase in the catalytic performance of the newly-synthesized ruthenium precatalysts, at high temperatures, is attributed to . . .
