Gold-catalysed tuning of reactivity in allenes: 9-endo hydroarylation versus formal 5-exo hydroalkylation.
The divergent gold-catalysed reactivity (C(sp(2))-H versus C(sp(3))-H) of aryloxy-tethered allenes has been uncovered.
متن کاملA new gold-catalysed azidation of allenes.
A new gold-catalysed azidation reaction of allenes is presented as a new highly modular approach for the synthesis of substituted allyl derivatives containing nitrogen from simple precursors.
متن کاملROMP Reactivity of endo- and exo-Dicyclopentadiene
The activation parameters for the ring-opening metathesis polymerization (ROMP) of endo(1) and exo-dicyclopentadiene (2), endo-1,2-dihydrodicylopentadiene (3), and norbornene (4) in the presence of Grubbs’ catalyst were determined using in situ NMR. The exo isomer of DCP was found to be more than an order of magnitude more reactive than the endo isomer. endo-DCP was found to have reactivity sim...
متن کامل2-exo,5-endo,8,8,10-Pentachlorobornane
The title compound, C(10)H(13)Cl(5), is a polychlorinated monoterpene and a Toxaphene congener. This compound is also the only penta-chlorinated derivative of camphene formed via ionic chlorination. Previously, the title compound was thought to be 2-exo,5-endo,9,9,10-penta-chloro-bornane, but X-ray structural analysis showed it to have a different structure and rather to be 2-exo,5-endo,8,8,10-...
متن کاملGold(I)-catalysed cycloisomerisation of 1,6-enynes into functionalised allenes.
1,6-Enynes can be transformed into vinylidenecyclopentanes via gold-promoted 5-exo dig cyclisation followed by 1,5-hydride or -alkoxide shift.
