A new method of synthesis of functionally substituted α-bromoallenes on the basis of 1,4-dibromobuta-1,2-diene has been developed. α-Bromoallenes are shown to react with nucleophilic reagents with allene-acetylene rearrangement thus affording high yields of functionalized acetylenic derivatives of hitherto unknown types. In contrast to this, the interaction of methyl 4-bromobuta-1,2-dienoate with amines
