Abstract: | C7H8Mo(CO)3 reacts with HBF4 and HCl by protonation of the ring ligand and formation of [C7H9Mo(CO)3]BF4 (I) and C7H9Mo(CO)3Cl (II), respectively. The compounds are characterised by means of their IR and NMR data. The reaction of I with P(C6H5)3 does not lead, as expected, to [C7H9Mo(CO)3P(C6H5)3]BF4 (III) but to the phosphonium salt [C7H9P(C6H5)3]BF4 (IV), i.e. nucleophilic addition of the phosphine at the cycloheptadienyl group takes place. The structure of IV has been determined by 13C NMR measurements. |
