Halogenoborane mediated allene cyclooligomerization

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))(...
