## Abstract Six examples of the Ξ²,Ξ²β€²,Ξ³,γ′‐tetraoxo phosphorus ylides 6 have been prepared. While they are found, upon flash‐vacuum pyrolysis (FVP) at 500Β°C to decompose to give no useful products, conventional pyrolysis by distillation at 200Β°C gives the trioxo alkynes 12 and 13 where R^1^ and R^2^

Reaction of a range of bis(ylides) with acid chlorides has been used to prepare the bis(oxoylides) 11-15. Similarly a range of simple ylides react with bis(acid chlorides) to give bis(oxoylides) 19-27 with the isomeric structure. Flash vacuum pyrolysis (FVP) of one example of the first type results
