First example of 1,1-bimetalloalkenes of tellurium and zirconium: Application for stereoselective preparation of (Z)-α-organotelluro-α,β-unsaturated carbonyl compounds
摘要:
Hydrozirconation of acetylenic tellurides 1 affords the first examples of 1,1-bimetalloalkenes of tellurium and zirconium 2. Intermediates 2 are reacted with acyl halides to obtain (Z)-alpha-organotelluro- alpha,beta-unsaturated carbonyl compounds 4 via Zr-Cu transmetallation. Copyright (C) 1996 Elsevier Science Ltd

Hydrozirconation of acetylenic tellurides 1 gives
organozirconium(IV) complexes 2, which are trapped with
tellurenyl iodides to afford ketene telluroacetals 3.
