2-arylvinylation of 1-methylindole by palladium-catalyzed cross-coupling reactions

Palladium-catalyzed cross-coupling of (1-methylindol-2-yl)zinc chloride (1) with 2-(bromoethenyl)arenes 2a-e provides 2-(2-arylethenyl)-1- methylindoles 3a-e in good yields. The alkenes (Z)-2b,c,e are coupled with retention of stereochemistry. With (Z)β-bromo-4-nitrostyrene [(Z)-2d], only (E)-3d is obtained whose structure has been confirmed by single-crystal X- ray diffraction.

A Convenient Stereoselective Reduction of Gem-Dibromides with a Combination of Dimethyl Phosphite and Potassium Carbonate

An efficient and highly stereoselective reduction of a gem-dibromocyclopropane to the corresponding monobromocyclopropane under mild reaction conditions was developed using a combination of dimethyl phosphite and potassium carbonate. This reaction provided a simple and practical way for the synthesis of the valuable monobromocyclopropanes and β-monobromoalkenes.

Ionic liquid-promoted stereoselective synthesis of (Z)-vinyl bromides by [bmIm]OH under organic solvent-free conditions: A green approach

A simple and easily accessible ionic liquid, 1-butyl-3-methylimidazolium hydroxide ([bmIm]OH), has been demonstrated as an efficient promoter and reaction medium for the highly stereoselective synthesis of (Z)-vinyl bromides by the debrominative decraboxylation of dibrominated α,β-unsaturated carboxylic acids in high yields. The reaction does not require either a conventional base or an organic solvent. Copyright Taylor & Francis Group, LLC.
