An efficient, stereospecific Cu-mediated catalytic system (CuI/20) has been developed for the synthesis of aryl vinyl ethers (Schemes 5 and 6).26 Ligand 20 was shown to be very effective in these processes. The method is useful because of the mild reaction conditions, broad functional group ...
A survey is given of investigation carried out on compounds (π-C5H5)2MRn, where M=Ti, V, Zr, Nb and R is an alkyl, aryl, or allyl group. Many results not previously published are included.doi:10.1016/S0020-1693(00)93371-1H.J. de Liefde Meljer...
In the case of 3-methyl allyl and related aryl selenides, characteristic δ-hydrogen migration to the selenium atom is observed. A McLafferty-type rearrangement is found in benzyl allyl selenides and substituted alkyl allyl selenides. The charge on the rearrangement products preferably remains on ...
A gram-scale reaction and the functional group transformation of products were conducted to further demonstrate the synthetic versatility of this catalytic transformation. Firstly, 1.21 g desired hydroxyl-containing product9was obtained with 4 mmol allyl alcohol as the starting materials under the ...

cyclohexane and substituted cyclohexane. Alkene groups of vinyl, allyl, butenyl and pentenyl are acceptable, as are dienyls such as butadienyl and pentadienyl. Mono-unsaturated cyclic hydrocarbon radicals and di-unsaturated cyclic hydrocarbon radicals containing rings with 5-7 carbon atoms are acceptable...
Synthesis of alkenes: claisen rearrangement of allyl vinyl ethers, part i; mechanistic views; the organic chemistry notebook series, a didactical approach, N2 9 This is the tenth theoretical assay in the series: "The Organic Chemistry Notebook Series, a Didactical Approach". The aim of this ...
Entgegen der Theorie wird jedoch eine unsymmetrische Bindung der Allyl-Gruppe an Lithium beobachtet mit Li-Abständen zu den terminalen C-Atomen Li C(1) 225.5(5) und Li C(3) 272.0(4) pm. Die C3H5-Einheit is nicht planar. Das zentrale H(2)-Atom is schwach zum Li-Atom hin ...
