R. Hara et al., Reduction of molybdenum(V) chloride with various reducing metals: Reactivity correlations with the descendant Lewis acids, CHEM LETT, (2), 2000, pp. 140-141
Reactivity of low-valent molybdenum prepared from MoCl5 with various reduci
ng metals in DME, was dependent on the reducing metals in the order of Al >
Sn, In > Zn, Mg, Li in the case of cyclotrimerization of alkynes. This ord
er is par allel to the acidity of the descendant Lewis acids.
