Abstract

A hitherto unknown triphosphatricyclo[3.2.1.0^2,7]oct-3-ene was obtained in high yield by a total of four consecutive pericyclic reactions from di-2-pyrone and excess TMS-C [triple bond, length as m-dash] P. DFT calculations gave insight into the reaction mechanism. The chiral phosphorus cage readily forms coordination compounds with Au(I) and Cu(I).
