Isolation of a Neutral P8 Cluster by [2+2] Cycloaddition of a Diphosphene Facilitated by Carbene Activation of White Phosphorus

摘要

The industrial preparations of organophosphorus compounds typically utilize chlorinated phosphorus starting materials, which are derived from readily available white phosphorus (P4). Ideally, more sustainable and environmentally benign processes would directly convert P4 into useful organophosphorus products. For this reason, the activation of P4 as opposed its chlorination and subsequent functionalization has become a topical objective.
