A useful intermediate for organorhenium complexes is the alkyne complex 2 , which can be formed from the tetrachloride 1 . In the presence of catalytic amounts of HBF 4 2 can undergo reaction with ethene and 2‐butene to give the 1,3‐diene complexes 3 and 4 respectively. Cl/ligand exchange is observed with 1‐butyne and acetonitrile in the presence of equimolar amounts of HBF 4 , but no CC bond formation occurs.
