The reaction of acetophenone hydrazones with TeCl4 in the presence of DBU gave a mixture of divinyl ditellurides and divinyl tellurides, which easily reacted with Cu powder in refluxing toluene to afford divinyl tellurides in good yields. The reaction of divinyl tellurides with bromine (1.2 eq.) gave the corresponding tellurium dibromide rather than the addition of the double bond whereas 3 molar amount of bromine gave excess brominated and oxidized products. The reaction of divinyl tellurides with 2-(trimethylsilyl)phenyl triflate in the presence of CsF gave (E)-2-alkenyldiaryl tellurides in good yields.

1,2-Dihalogenation and oxy-1,1-dihalogenation of alkynes by N-halosuccinimides can be selectively realized through using different reaction conditions. α,β-Dihalo alkenes were obtained exclusively using THF as solvent without using any catalyst, while α,α
Vinyl Cation Intermediates in Solvolytic and Electrophilic Reactions. 2. Bromination of Arylacetylenes
Yates, Keith,Mandrapilias, George
, p. 3902 - 3906 (2007/10/02)
The kinetics of bromination of a series of ten ring-substituted phenylacetylenes were investigated in anhydrous acetic acid at 25 deg C.All substrates were substituted with one or two methyl groups at the ortho position(s) for comparison with the behavior
