New and efficient methods were developed to prepare ketene organyltelluroacetals in moderate to excellent yields. This was accomplished by reaction of phenyl- or butyltelluromethylphosphonates with phenyl- or butyltellurenyl halides and aldehydes or cyclo
One-pot synthesis of telluroketene acetals and haloketene acetals using sp2 geminated hetero organobismetallic intermediates
Guerrero Jr., Palimécio G.,De Oliveira, Paulo R.,Baroni, Adriano C.M.,Marques, Francisco A.,Labes, Ricardo,Dabdoub, Miguel J.
experimental part, p. 1582 - 1586 (2012/04/10)
A novel one-pot synthesis of 1,1-dihalo-1-alkenes and 1,1-bis(butyltelluro) -1-alkenes was developed from hydrozirconation of alkynylzinc bromide with Cp2Zr(H)Cl and subsequent capture of the Zn/Zr 1,1-heterodimetallo-1- alkene intermediates wi
Hydrozirconation of acetylenic chalcogenides. Synthesis and reactions of zirconated vinyl chalcogenide intermediates

Acetylenic tellurides react with Cp2Zr(H)Cl in THF at room temperature to give the α-zirconated vinyl telluride intermediates 39, which react with a wide range of electrophiles to give several types of trisubstituted olefins, such as α-halo vin
