摘要

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 in extrusion of Ph3P rather than the expected Ph3PO while six examples of the second type do extrude Ph3PO upon FVP at 500° C to afford the bis ( ...
