Abstract
The reaction of the chromium anionic carbene complex 1 towards dipheny lacetylene and phenylacetylene is reported. In the former case the syn thesis of gamma-functionalized butenolides results after demetallation of the chromium complex 2 and the latter leads to the formation of a novel oligomer chromium complex 5. These complexes were characterized by mass spectrometry, IR and H-1 and C-13 NMR spectroscopies and their structures were confirmed by single-crystal X-ray analysis. (C) 1997 Elsevier Science S.A.
