Quantitative Determination of the Regioselectivity of Nucleophilic Addition to η(3)-Propargyl Rhenium Complexes and Direct Observation of an Equilibrium Between η(3)-Propargyl Rhenium Complexes and Rhenacyclobutenes

PMe(3) adds selectively to the central carbon of the η(3)– propargyl complex [C(5)Me(5)(CO)(2)Re(η(3)-CH(2)C≡CCMe(3))][BF(4)] (1-t-Bu) to form the metallacyclobutene [C(5)Me(5)(CO)(2)Re(CH(2)C(PMe(3))=CCMe(3))][BF(4)] (7). The rate of rearrangement of the metallacyclobutene 7 to η(2)-alkyne complex...
