Mononuclear Phenolate Diamine Zinc Hydride Complexes and Their Reactions With CO.

The synthesis, characterization, and zinc coordination chemistry of the three proligands 2--butyl-4-[-butyl ()/methoxy ()/nitro ()]-6-{[(2'-dimethylaminoethyl)methylamino]methyl}phenol are described. Each of the ligands was reacted with diethylzinc to yield zinc ethyl complexes -; these complexes were subsequently reacted with phenylsilanol to yield zinc siloxide complexes -. Finally, the zinc siloxide complexes were reacted with phenylsilane to produce the three new zinc hydride complexes -.
