Abstract
Few monobenzannulated 1-boraindene compounds have been reported. Here we report the synthesis of two 1-boraindenes, accessed by a bond-breaking and -making cascade from a secondary borane and diolefin, mediated by a simple pentamethylcyclopentadienyl-ligated rhodium(i) complex, [(Cp*)Rh(η2, η2-NBD)] (Cp* = C5Me5−, NBD = norbornadiene).
