Addition of MeMgSnBun3 to Terminal Enyne; Preparation of Geometrically Pure 2-Substituted 1-Iodo-1,3-Dienes

The title iododienes have been prepared from 6-phenylhex-3-en-yne by the addition of methylmagnesiumtributyltin, followed by reactions of stannylmagnesium intermediate A with appropriate electrophiles and of the resulting alkylated stannylidiene B with iodine.

Sequestered alkyllithiums: Why phenyllithium alone is suitable for betaine-ylide generation

The key step in the trans-selective modification of the Wittig reaction is the α-lithiation of the lithium bromide coordinated ylide - aldehyde adduct (the so-called "P-betaine"). Only phenyllithium effects this deprotonation rapidly and cleanly. Alkyllithiums (in particular, butyl-, sec-butyl-, and tert-butyllithium) react only sluggishly and incompletely, being tied up in very stable mixed aggregates with the lithium alkoxide part of the betaines.

Electrophilic fluorodesilylation of allenylmethylsilanes: A novel entry to 2-fluoro-1,3-dienes

(Chemical Equation Presented) Various fluorodienes were prepared by treatment of the corresponding allenylmethylsilanes with Selectfluor. This is the first route to these compounds not based on the use of a fluorinated building block. The reaction allows

Rearrangement of Allylic and Propargylic Alcohols Catalyzed by the Combined Use of Tetrabutylammonium Perrhenate(VII) and p-Toluenesulfonic Acid

Allylic rearrangement and/or dehydration of allylic alcohols proceed by the use of a catalytic amount of tetrabutylammonium perrhenate and p-toluenesulfonic acid.Treatment of propargylic alcohols with the above reagents affords the rearranged products, α,β-unsaturated carbonyl compounds.
