Solvent Incorporation in Bromination of Alkynes With Tetrabutylammonium Tribromide in Methanol
The reaction of tetrabutylammonium tribromide (TBABr 3 ) with mono and disubstituted alkynes in methanol at 20°C leads to the formation of mainly the corresponding α,α-dibromo, β,β-dimethoxyalkane and the E-(α,β)-dibromoalkene. The additions are faster using sonication.
