Description and Uses

Reactant for:

• Preparaton of a-substituted alkylsilanes via regio- and chemoselective copper-catalyzed silylzincation and electrophilic substitution from terminal alkenes, and prepn. of α-substituted alcohols via Fleming-Tamao oxidation of alkylsilanes
• Olefin isomerization with Grubbs′ catalysts occluded in a hydrophobic matrix of polydimethylsiloxane (PDMS)
• C9-substituted trans-hydrindene via diastereotopic group-selective intramolecular Diels-Alder reaction
• Isomerization of allyl group-containing compounds to propenyl group-containing compounds in the presence of a Grubbs second-generation Ru catalyst
• Ruthenium-catalyzed olefin cross-metathesis of vinyl and allyl phosphine oxides to give alkenyl phosphine oxides and bis-phosphine oxides
