Let α be a Lie algebra over a field of characteristic zero equipped with a vector space decomposition α s α y [ α q , and let s and t be commuting formal variables y ww xx q ww xx commuting with α. We prove that the map C: sα s, t = t α s, t Βͺ y ww xx q ww xx sα s, t [ t α s, t defined by the Campbe
