HBr and DMPU (1,3‐dimethyl‐3,4,5,6‐tetrahydro‐2‐pyrimidinone) form a room‐temperature‐stable complex that provides a mild, effective, and selective hydrobrominating reagent toward alkynes, alkenes, and allenes. HBr–DMPU could also replace other halogenating reagents in the halo‐Prins reaction, ether cleavage, and deoxy‐bromination reactions.
HBr和DMPU(1,3-二甲基-3,4,5,6-四氢-2-嘧啶酮)形成室温稳定的络合物,为炔烃,烯烃和丙二烯提供温和,有效和选择性的氢溴化试剂。HBr-DMPU还可以取代卤代普林斯反应,醚裂解和脱氧溴化反应中的其他卤化试剂。
