A highly strained, thermally stable (up to 150 °C) branched phospha[7]triangulane was synthesized from the second-generation bicyclopropylidene and transient phosphinidene [Ph?P=W(CO)5], followed by demetalation in refluxing xylene. Bulkier transient CuCl?alkene-complexed phosphinidene gave 2-phosphabicyclo-[3.2.0]hept-1(5)-ene as an additional product. The "outer sphere" spirocyclopropanes provide a stabilizing factor for both of these novel compounds. Copyright
