Observation of a π- to σ-rearrangement upon proton addition to bicyclo[6,1,0]nonatrienetricarbonylmolybdenum
Abstract
Proton addition to bicyclo[6,1,0]nonatrienetricarbonylmolybdenum (I) gives complex (II) in which a π- to σ-rearrangement has taken place with σ-bonding between Mo and C(2) and π-bonding between Mo and the pentadienyl C(3)–C(7).
