3-溴苯甲醛是一種有機化合物，化學式為C7H5BrO。它在室溫為無色液體。[6]

製備

3-溴苯甲醛可由苯甲醛和溴在氯化鋁催化下、在1,2-二氯乙烷中於40-45°C反應得到；[7]或通過3-溴苯甲醇的催化氧化反應製得。[8][9]

3-溴苯甲醛肟和四氯化鈦、碘化鈉在乙腈中反應，也能得到3-溴苯甲醛。[10]

性質

3-溴苯甲醛的C–Br鍵和醛基都可發生反應。例如，它可以和苯硼酸在鈀催化劑和鹼的存在下發生鈴木偶聯反應（C–C偶聯），得到聯苯-3-甲醛：[11][12]

3-溴苯甲醛參與的C–C偶聯反應

它和活潑亞甲基化合物可以發生克腦文蓋爾縮合反應，例如和氰乙酸乙酯反應，生成3-(3-溴苯基)-2-氰基丙烯酸乙酯[13]；和丙二腈反應，生成3-溴亞苄基丙二腈[14]：

3-溴苯甲醛的醛基和活潑亞甲基化合物（氰乙酸乙酯）反應
3-溴苯甲醛的醛基和活潑亞甲基化合物（丙二腈）反應

它和胺可以發生C–N偶聯反應，如和苄胺反應，得到N-(3-溴亞苄基)苄胺；[15]和4-氨基嗎啉反應，得到N-(3-溴亞苄基)氨基嗎啉。[16]

其醛基也可以發生氧化還原反應，如它可以被硼氫化鈉還原為3-溴苯甲醇[17]；在鈀催化下被氫氣還原為3-溴甲苯[18]；或者被氧氣[19]、過氧化叔丁醇[20]等氧化劑氧化為3-溴苯甲酸。
