Facile generation of α,α-dibromodimethyl ketals from alkynes using TsNBr2
摘要:
TsNBr2 reacts with alkyne in the presence of methanol to form alpha,alpha-dibromodimethyl ketals instantaneously. The reaction proceeds smoothly at room temperature without using any other catalyst. The one step reaction can be carried out with both aromatic and aliphatic alkynes in excellent yield. (C) 2014 Elsevier Ltd. All rights reserved.
