Fragmentation Reactions of Bridged Heterocyclic Phosphorus Compounds as a Source of Low-Coordination Species

摘要

Several types of unsaturated, bridged structures have been prepared that can undergo retro-cycloaddition with the extrusion of phosphorus species having low coordination. By this technique, the species RO-PO2, R-PO2, R2N-P=S, RO-P=S, and R-P=CH2 have been generated and detected by trapping experiments.
