资源简介：
The first transition-metal–oxetylidene complex
has been prepared by reaction of OsCl(η5-C5H5)(CO)(PiPr3) with 3,3-di(methoxycarbonyl)-5-hexyn-1-al and AgBF4. This novel compound is transformed into a hydroxyalkenylcarbene
isomer by deprotonation and subsequent protonation of the resulting
α,β-unsaturated acyl transient species. In fluorobenzene
at 90 °C, the four-membered ring undergoes cycloreversion to
afford a cis-dicarbonyl derivative and the cycloalkene.
