The first non-cluster bond between boron and beryllium has been reported by scientists in Germany.
10 years ago, few reactions existed where boron behaved as an nucleophile. That all changed with the advent of lithium diazaborolide in 2006, and boron has been partnering up with myriad main-group, transition metal and lanthanide elements ever since. However, despite beryllium sitting right next to boron in the periodic table, a classical two-centre/two-electron bond had never been reported between the two neighbours, until now.
