title: Synthesis of cyclic diborenes with unprecedented cis-configuration.
abstract: The first examples of cis-configured diborenes - and the first cyclic diborenes - are isolated by taking advantage of stabilisation by chelating diphosphine ligands. The diborenes are prepared by a convenient one-pot reductive procedure that circumvents the need for a pre-formed base-adduct of the boron-containing precursor.
