✦ Synopsis
Platinum complexes / Carbene platinum complexes / Carbene zirconium complexes / Carbene complex synthesis, non-nucleophilic / Zirconium complexes While (q4-butadiene)zirconocene and -hafnocene do not react with Pt(PPh,),(CO), (2) in toluene solution at room temperature, cp2Zr(q4-C4HG) (1 a: cp = q5-C5H5; 1 b: cp = q5-C5H4CH3) reacts with cis-Pt(C6F5],L(CO) (3 L = CO; 5: L ' = PiPr,) under similar conditions to give the metallacyclic Fischer-type car-bene complexes cp,ZiOC[ = Pt(C6F5)2L]C4H6 ( 4 L = CO; 6 L = PiPr,). When L = CO, isomerization takes place by UV irradiation (cis-4 $ trans-4) presumably as the result of a dissociative CO scrambling process. This is not observed when L = PiPr,.
