The halogenoboranes XB(C 6 F 5 ) 2 (X: Cl, Br) react with allene to give a mixture of the cyclotrimer 1,3,5-trimethylenecyclohexane ( 1 ) and the related halogenoborylated cyclotetramerization products 3a and 3b . Alkyl-substituted allenes were catalytically cyclotrimerized metal-free by XB(C 6 F 5...
