Abstract
The dimer [C6H6Mo(π-C3H6)Cl]2 is cleaved by chelate ligands L2 giving the cations [C6H6Mo(π-C3H5)L2]+[L2= Ph2PCH2CH2PPh2(dppe), Me2PCH2CH2PMe2(dmpe), or (MeSCH2)2]. The cations react with nucleophiles (R–= H–, Bun, and, when L2= dppe, CN–) giving the neutral cyclohexadienyl derivatives [(C6H6R)Mo(π-C3H5)L2]. An asymmetric structure for the latter is suggested by 1H n.m.r. spectra at 270 MHz and double-resonance experiments. The cations [(C6H6R′)Mo(π-C3H5)L2′]+, (R′= H or Me, L2′= en, bipy, and o-phenylenediamine) are also described.Keywords
