摘要：
Give me five: Group VI metal quintuple bonds undergo Friedel-Crafts-type haloacylation reactions. Treatment of the quintuple-bonded molybdenum complexes with one equivalent of acyl halides RCOX (R=Me, C6H5, 2-MeC6H4; X=Cl, Br), yields metal-metal quadruple-bonded acyl complexes. Subsequent treatment with a second equivalent of acyl halides causes disproportionation of two acyl groups to give dimolybdenum carbyne carboxylate complexes.
