STEREOSELECTIVE CARBONYL OLEFINATION VIA ORGANOSILICON COMPOUNDS. BORON AND TITANIUM REAGENTS

Abstract
Boron reagents derived from trialkylsilylacetonitrites are effective for the synthesis of Z-α,β-unsaturated nitriles. Z-Terminal enyne units are synthesized from the titanium reagent from 1,3-bis-(trimethylsilyl)propyne and aldehydes.
