Improved metathesis lifetime: chelating pyridinyl-alcoholato ligands in the second generation Grubbs precatalyst
Du Toit, Jean I.; Huijsmans, Carlijn A.A.; Jordaan, Johannes H.L.; Van Sittert, Cornelia G.C.E.; Vosloo, Hermanus C.M.; Jordaan, Margaritha (MDPI, 2014)Hemilabile ligands can release a free coordination site “on demand” of an incoming nucleophilic substrate while occupying it otherwise. This is believed to increase the thermal stability and activity of catalytic systems ... -
Industrial viability of homogeneous olefin metathesis: beneficiation of linear alpha olefins with the diphenyl-substituted pyridinyl alcoholato ruthenium carbene precatalyst
Du Toit, Jean I.; Loock, Monique M.; Tole, Tegene T.; Marx, Sanette; Jordaan, Johannes H.L.; Vosloo, Hermanus C.M. (Elsevier, 2016)The catalytic performance of the diphenyl-substituted pyridinyl alcoholato ruthenium carbene precatalyst of the Grubbs 2-type was optimized for 1-octene metathesis by varying operating parameters, such as reaction temperature ... -
α-Pyridinyl alcohols, α,α’-pyridine diols, α-bipyridinyl alcohols, and α,α’-bipyridine diols as structure motifs towards important organic molecules and transition metal complexes
Tole, Tegene T.; Jordaan, Johannes H.L.; Vosloo, Hermanus C.M. (Bentham, 2020)Background: The preparation and use of pyridinyl alcohols as ligands showed incredible increment in the past three decades. Important property of pyridinyl alcoholato ligands is their strong basicity, which is mainly due ...
