The reaction behavior of silylvinylmethanols with acid catalysts was investigated. The starting silylvinylmethanols 2 were prepared by the reaction of the corresponding α,β-unsaturated acylsilanes 1 with organocerium reagents. The reaction of 2 with TsOH

2-Trimethylsilyl-1-oxa-1,3-butadiene (7) reacts with Fe2(CO)9 to form an unstable tetracarbonyliron (0) complex (8) whereas 2-trimethylsilyl-4-phenyl-1-oxa- 1-oxa-1,3-butadiene (9) and 2-(tert-butyldimethylsilyl)-4-phenyl-1-oxa-1,3-butadiene (20) react with Fe2(CO)9 to form highly stable crystalline tricarbonyliron(0) complexes (16 and (21). Complexes (16) and (21) both undergo acylation when reacted with methyl lithium under nitrogen to form γ-ketoacylsilanes [(18) and (22)], but only complex (21) reacts with methyl lithium under carbon monoxide to give the tricarbonyl(vinylketene)iron(0) complex (23).
Rearrangement of allylic and propargylic alcohols catalyzed by the combined use of tetrabutylammonium perrhenate(VII) and p-toluenesulfonic acid
Narasaka,Kusama,Hayashi
, p. 2059 - 2068 (2007/10/02)
Allylic rearrangement and/or dehydration reaction of allylic alcohols proceeds smoothly by the use of catalytic amounts of tetrabutylammonium perrhenate and p-toluenesulfonic acid hydrate. Treatment of propargylic alcohols with the catalysts at room temperature affords the rearranged products, α,β-unsaturated carbonyl compounds, while β,γ-unsaturated ketones are obtained as main products by the reaction in refluxing 1,2-dichloroethane. The application of this catalytic system is also described for the preparation of some synthetic intermediates.
