摘要

Six very soluble paddlewheel compounds containing Mo_2~(n+)units,n=4,5,6,and two alkyl-substituted bicyclic guanidinate ligands have been synthesized.The quadruply bonded complexes with n=4,Mo2(TMhpp)4 and Mo2(TEhpp)4,(TMhpp=the anion of 3,3,9,9-tetramethyl-1,5,7-triazabicyclo[4.4.0]dec-4-ene and TEhpp=the anion of 3,3,9,9-tetraethyl-1,5,7-triazabicyclo[4.4.0]dec-4-ene)are easily oxidized.The electrode potentials in THF are-1.08 and-1.17 V vs.Ag/AgCl,respectively,for the Mo_2~(5+/4+)couple.These potentials are in accord with the low ionization potentials for the quadruply bonded compounds.Because of the high solubility of the Mo_2~(4+)compounds in most common organic solvents they are attractive candidates for use as strong reducing agents in homogeneous systems.
