Mixtures of OXONE ® and hydrobromic acid or hydrochloric acid afford solutions of bromine or chlorine, respectively. α-Bromo- or α-chloro-α,β-unsaturated carbonyl compounds were prepared by addition of hydrobromic acid or hydrochloric acid to the mixture of α,β-unsaturated carbonyl compounds and OXONE ® in CH2Cl2 followed by treatment of Et3N in moderate to good yields.
OXONE®和溴化氢或盐酸的混合物分别提供溴或氯的溶液。通过将溴化氢或盐酸加入含有α,β-不饱和羰基化合物和OXONE®的CH2Cl2混合物中,然后用三乙胺处理,可以制备出α-溴或α-氯-α,β-不饱和羰基化合物, yields 从中等到良好。
