Aryl substituent effects on the thermal interconversion of cyclobutenediones and 1,2-bisketenes

The rates and activation parameters are reported for ring closure of 1,2 bisketenes O=C=C(C6H4X)C(SiMe3)=C=O (7), generated by photolysis of the corresponding cyclobutenediones 6. The rates at 70°C are correlated with the

A stabilized and persistent tetraketene: 1,4-bis(1',4'-dioxo-3'-trimethylsilyl-2'-buta-1',3'-dienyl)benzene

Reaction of 1,4-bis(trimethylsilylethynyl)benzene with CCl3COCl and Zn gave 1,4-bis(4',4'-dichloro-2'-trimethylsilyl-3'-oxo-1'-cyclobutenyl)benzene (7), which reacted with concentrated H2SO4 at 87 degC to give 1,4-bis(2'-trimethylsilyl-3',4'-dioxo-1'-cycl
