摘要：

The reaction of pentacarbonyl[ethoxy(phenylethynyl)carbene]chromium with silyl enol ethers yields cyclobutenylcarbene complexes in moderate-to-good yield by a process that involves a Michael-type addition of the nucleophilic enol ether to the Fischer carbene complex. An ene-type product and two pyranylidene chromium complexes were also obtained in these reactions. A pyranylidene complex was also obtained in the reaction of the related tungsten complex with (Z)-1,3-bis(trimethylsilyloxy)-1-ethoxy-1,3-butadiene.
