A very stable heterogenized difunctional cyclopentadienyl-ring precursor, storable under ambient conditions, readily participates in the simultaneous formation of a η5 bond with a [fac-Re(CO)3]+ species and a σ bond with heteroatom (halides, carboxylates) or carbon nucleophiles (boronic acids) to produce halo-, acyloxy-, or carbon-substituted cyclopentadienyl–Re(CO)3 complexes in a one-pot reaction in yields of between 41 and 71 % [Eq. (1)]. No catalyst is required and unprotected (usually) sensitive functional groups are well tolerated.
