11. Recently, we successfully used this complex described by Herrmann et al. [Herrmann, W. A.; Brossner, C.; Öfele, K.; Reisinger, C-P.; Priermeier, T.; Beller, M.; Fischer, H. Angew. Chem. Int. Ed. Engl. 1995, 34, 1844-1848] for the cyclization of (E)-2-(1-alkynyl)-3-aryl/alkylpropenoic acids to the corresponding (E)-3-ylidene-3H-furan-2-ones (see: Ref 10d).

3N according to the general procedure described by Lu et al. for the synthesis of (Z)-γ-ylidenebutenolides [Lu, X.; Huang, X.; Ma, S. Tetrahedron Lett. 1993, 34, 5963-5966]. Unfortunately, this reaction did not provide 5a but afforded 1,4-diphenylbutadiyne and a compound to which, on the basis of its MS spectrum, we tentatively assigned the structure of 1,2,4-triphenylbenzene.
