The dialkynylated eta(6)-(arene)Cr(CO)(3)-complexes 2 and 3 can be synthesized: (a) by Sonogashira coupling Of alkynes with dihalo areneCr(CO)(3)-complexes: or (b) very efficiently by a Horner-Emmons-Wadsworth related acetylene synthesis with readily available Cr(CO)(3)-complexed aryl aldehydes. The structural constitution of two novel difunctional alkynyl arene complexes (2a and 6) was confirmed by X-ray crystal structure analyses. (C) 1999 Elsevier Science S.A. All rights reserved.
