title: Unusual product formation in a 1,1-carboboration reaction.
abstract: The reaction of the cross-conjugated enediyne Me2C[double bond, length as m-dash]C(C[triple bond, length as m-dash]CSiMe3)2 () with B(C6F5)3 gives the unusual borabicyclo[4.3.0]nonadiene product . The reaction sequence is initiated by 1,1-carboboration and is suggested to take a short subsequent sequence involving borane induced H migration reactions from the geminal pair of methyl groups.
