Influence of a methyl substituent on the Raman spectrum of but-3-enyl methyl ether
Bowen, Richard D.,Edwards, Howell G.M.,Varnali, Tereza
, p. 26 - 32 (2012)
The Raman spectrum of but-3-enyl methyl ether, CH2=CHCH 2CH2OCH3 is reported and compared with those of its homologues in which a methyl group is substituted for a hydrogen atom on one of the carbon atoms of the alkenyl chain. Attention is focused on the influence of this methyl group on the bands in the spectrum associated with specific C-H, skeletal stretching and bending vibrations. The use of ab initio DFT quantum mechanical calculations to assist in making these assignments reveals a high degree of mode-mixing in the skeletal vibrations. The value of model studies of this kind in refining the correlations between the presence and absence of specific bands in a Raman spectrum with molecular structure is emphasised.
Expedient Access to 2,3-Dihydropyridines from Unsaturated Oximes by Rh(III)-Catalyzed C-H Activation

α,β-Unsaturated oxime pivalates are proposed to undergo reversible C(sp2)-H insertion with cationic Rh(III) complexes to furnish five-membered metallacycles. In the presence of 1,1-disubstituted olefins, these species participate in irreversible migratory insertion to give, after reductive elimination, 2,3-dihydropyridine products in good yields. Catalytic hydrogenation can then be used to convert these molecules into piperidines, which are important structural components of numerous pharmaceuticals.
Homogeneous Catalysis. Use of the Catalyst for the Sakurai Reaction of Allylic Silanes with Orthoesters, Acetals, Ketals and Carbonyl Compounds.
Hollis, T. Keith,Robinson, N. P.,Whelan, John,Bosnich, B.
, p. 4309 - 4312 (2007/10/02)
The effectiveness of the catalyst for the Sakurai reaction has been explored for a variety of allylic silanes reacting with orthoesters, acetals, ketals, aldehydes and ketones. Key Words: Sakurai reaction, titanium based catalyst.
CATALYTIC ACID DEHYDROCHLORINATION OF TERTIARY AND BENZYLIC CHLORIDES
Arakelyan, A. S.,Dvoryanchikov, A. I.,Gevorkyan, A. A.
, p. 1193 - 1196 (2007/10/02)
For the case of a series of tertiary and bezylic chlorides it was shown that elimination by the acid-catalyzed generation of cationoid intermediates is no less effective for the production of olefins than the widely employed alkaline dehydrochlorination.
Palladium-Catalyzed Addition of Methanol to Isoprene
Gaube, W.,Stegemann, H.
, p. 947 - 954 (2007/10/02)
The soluble systems containing palladium(II)-compounds and tri-n-butylphosphine as a ligand catalyze the addition of methanol to isoprene to give methoxyisopentenes in good yields.Activity and selectivity of the reaction are dependent on the ligand, the ratio ligand to palladium and in a surprising manner on the concentration of methanol.
