Aminocarbene annulation by alkynes: a regio- and diastereo-selective route to indanone complexes
Abstract
Upon reaction with oct-1-yne, pentacarbonyl[allylamino(2-methoxyphenyl)methylene]chromium undergoes a regio- and diastereo-selective carbene annulation leading finally to a syn-tricarbonyl(3-hexyl-7-methoxy-indanone)chromium complex, the crystal structure of which has been established by X-ray analysis.
