  Abstract A series of substituted-cyclopentadienyl molybdenum allyl derivatives has been prepared by reacting (η 3 -C 3 H 5 ) 3 MoCl with substituted-cyclopentadienyl and -indenyl alkali metal salts. In general, the isolated products are of the type Cp′Mo(η 3 -C 3 H 5 ) 2 and in three cases this has been confirmed by crystal structure determinations. Spectroscopic evidence suggests that at low temperatures

  A systematic ranking of different nucleophiles (including enolates, phenolates, thiophenolates, hydroxide, cyanide) with respect to their ability to stabilise the transition state of substitution reactions has been carried out in acetonitrile and dimethyl sulfoxide. The method is based on a comparison of the rate constant, k(SUB), for the substitution reaction between a given nucleophile and benzyl chloride with the rate constant, ka(ET), for the corresponding electron transfer from an aromatic radical anion to benzyl chloride. The ratio k(SUB)/k(ET) expresses the rate enhancement due to electronic interaction in the transition state, Delta G(sta), of the substitution reaction. In this study, k(SUB)/k(ET) ratios between 5 and 10(31) were determined corresponding to Delta G(Sta)-values of 4-175 kJ mol(-1). These values cover substitution reactions going from outer-sphere electron transfer to S(N)2 with partial bond formation in the transition state. The k(SUB)/k(ET) values are round to be largest for nucleophiles such as OH- and CN- with very poor electron-donating abilities thigh oxidation potentials). When different. types of nucleophile with similar oxidation potentials are compared, a decrease in k(SUB)/k(ET) is observed going from sulfur- to carbon- and further to oxygen-centred nucleophiles. The ranking of nucleophiles in reactions involving electrophiles other than benzyl chloride is discussed with emphasis on steric hindrance and electronic effects.
