Efficient catalytic alkyne metathesis with a fluoroalkoxy-supported ditungsten(III) complex
Beilstein Journal of Organic Chemistry, 2018 The molybdenum and tungsten complexes M2(OR)6 (Mo2F6, M = Mo, R = C(CF3)2Me; W2F3, M = W, R = OC(CF3)Me2) were synthesized as bimetallic congeners of the highly active alkyne metathesis catalysts [MesC≡M{OC(CF3)nMe3−n}] (MoF6, M = Mo, n = 2; WF3, M = W ...

The Living ROMP of trans-Cyclooctene [PDF]
, 2009 The living ring-opening metathesis polymerization (ROMP) of trans-cyclooctene (tCO) was investigated. ROMP of tCO in the presence of PPh_3 in THF leads to the formation of narrowly dispersed polycyclooctene (PCO).

Z-Selective Homodimerization of Terminal Olefins with a Ruthenium Metathesis Catalyst [PDF]
, 2011 The cross-metathesis of terminal olefins using a novel ruthenium catalyst results in excellent selectivity for the Z-olefin homodimer. The reaction was found to tolerate a large number of functional groups, solvents, and temperatures while maintaining ...

Study of cascade ring-closing metathesis reactions en route to an advanced intermediate of Taxol [PDF]
, 2016 A highly functionalized intermediate in the synthesis of Taxol has been synthesized, which features the tricyclic core and the required oxygen substituents at C1, C2, C7, C10 and C13. The key step, a ring-closing dienyne metathesis (RCDEYM) reaction, has
