“…[33] (S)-2-Methylbutylmagnesium chloride (7) was prepared from (ϩ)-(S)-1-chloro-2-methylbutane (6) (97.5% ee) as previously reported. [34] (R,S)-1-Bromo-1,2-butadiene (3a), 1-bromo-3-methyl-1,2-butadiene (3b) and (R,S)-1-bromo-3-methyl-1,2-pentadiene (3c) were synthesised and purified (70Ϫ90% yields) according to literature methods, [31] starting from the appropriate propargylic alcohols. Ϫ IR spectra were measured on KBr plates as neat films.…”

“…[32] The optically active acetylenes (S)-3-methyl-1-pentyne (1c), (S)-4-methyl-1-hexyne (1f) and (S)-5-methyl-1-heptyne (1g) were prepared by bromination-dehydrobromination [33] of the corresponding alkenes 4aϪc. Olefins 4aϪc were obtained from the Grignard reagent of (S)-1-chloro-2-methylScheme 2 butane (6, Ͼ97% ee) according to the synthetic strategies [34] described in Scheme 3. (S)-3-Methyl-1-pentene (4a) was prepared by the pyrolysis [35] (130°C, 1 Torr) of N,Ndimethyl(3-methylpentyl)amine N-oxide generated in situ by H 2 O 2 oxidation of the corresponding amine 8.…”

Solvated rhodium atoms, prepared by the metal vapour synthesis technique, promote the silylformylation reaction of variously substituted alkynes R 1 R 2 CH(CH 2 ) n CϵCH, with catalytic activities comparable with and even higher than more common species such as Rh 4 (CO) 12 . Z-Silylalkenals are exclusively formed in high yields (60−95%) indicating syn addition both of CO and of the silane (Me 2 PhSiH) to the triple bond. The chemoselectivity of the process (silylformylation vs. hydrosilylation) is highly affected by the amount of cata-

Die Hauptbestandteile des Fuselols (Isoamylalkohol und 2-Methyl-butanol-1) lassen sich nach Uberfuhrung in die Chloride durch extraktive Destillation mit 1,2-Dibrom-3-chlorpropan als Zusatzstoff trennen. Das Verfahren erfordert aber glaserne Kolonnen, da sich der Zusatzstoff unter dem katalytischen EinfluD von Metallen zersetzt. Die Chloride konnen ferner durch Fliissiglflussig-Extraktion mit dem System 1,2-Dibrom-3-chlor-propadGlyko1 + Methanol getrennt werden, jedoch liegt der Trennfaktor mit 1.09 nur wenig uber I. Eine vollstandige Trennung der Alkohole in die reinen Komponenten
