Evidence for a Concerted SN2' Mechanism in the Gas-Phase Acid-induced Nucleophilic Substitutions on Allylic Substrates
Dezi, Emanuela,Lombardozzi, Antonietta,Pizzabiocca, Adriano,Renzi, Gabriele,Speranza, Maurizio
, p. 547 - 548 (1995)
Gas phase nucleophilic substitution on oxygen-protonated but-1-en-3-ol and trans-but-2-en-1-ol by methanol proceeds via the concerted SN2' mechanism in competition with the classical SN2 mechanism.
THE cis REDUCTION OF 4-(TRIMETHYLSILYL)-3-BUTYN-2-OL WITH LITHIUM ALUMINIUM HYDRIDE
Mancini, Michael L.,Honek, John F.
, p. 4295 - 4298 (1983)
A systematic study led to a method for the preparation of (Z)-4-(trimethylsilyl)-3-buten-2-ol (2) in at least 99percent purity by the reduction of the alkyne 4-(trimethylsilyl)-3-butyn-2-ol (1) with lithium aluminium hydride (LAH) as a clear solvate in ether.
Probing Molecular Motion and Chemical Reactions inside the Chiral Tri-o-thymotide Clathrate Cavity by Solid State NMR Techniques
Facey, Glenn,Ripmeester, John A.
, p. 1585 - 1587 (1990)
Solid state NMR techniques offer a non-destructive alternative to wet chemistry methods in following enantiomeric excess and reactions in chiral clathrates, and show that the two optically distinct populations, one of which cannot be defined by X-ray diffraction, can be characterized by their distinct dynamic behaviour.

The vapor-phase dehydration of 1,3-butanediol (1,3-BDO) to produce 1,3-butadiene (BD) was evaluated over yttrium zirconate, which was prepared through a hydrothermal aging process. 1,3-BDO was initially dehydrated to three unsaturated alcohols, namely 3-buten-2-ol, 3-buten-1-ol, and 2-buten-1-ol, followed by the further dehydration to BD. The catalytic activity of yttrium zirconate was greatly dependent on the calcination temperature. Also, the reaction temperature was one of the important factors to produce BD efficiently. The selectivity to BD was increased with increasing reaction temperature up to 375°C, while coke formation resulted in catalyst deactivation together with by-product formation at higher temperatures. Yttrium zirconate catalyst calcined at 900°C showed a high BD yield of 95% at 375°C and 10 hr on stream.
Dehydration of 2,3-butanediol to produce 1,3-butadiene over Sc2O3 catalyst prepared through hydrothermal aging

Vapor-phase catalytic dehydration of 2,3-butanediol (2,3-BDO) to form 1,3-butadiene (BD) via 3-buten-2-ol (3B2OL) was studied over various single metal oxide catalysts. Among the catalysts, Sc2O3 prepared under hydrothermal (HT) conditions at 200 °C followed by 800 °C calcination showed the most excellent catalytic activity. The crystallization of precursor ScOOH during HT aging noticeably enhances the catalytic activity of the resulting Sc2O3 for the formation of 3B2OL in the dehydration of 2,3-BDO. The formation rate of 3B2OL from 2,3-BDO over the HT-aged Sc2O3 was twice as high as Sc2O3 without HT aging. Calcination temperatures of Sc2O3 are also important: calcination at 800 °C is efficient for the selective formation of 3B2OL from 2,3-BDO. The HT-aged Sc2O3 also showed an excellent catalytic activity for the formation of BD with the yield higher than 80% in the dehydration of 2,3-BDO at 411 °C.
