Synthesis and crystal structures of guanidinatoaluminum complexes and catalytic study for MPV reduction

The synthesis of four guanidinatoaluminum complexes is described. The molecular structures of four guanidinatoaluminuml complexes were confirmed by a single crystal X-ray diffraction study. In addition, the guanidinatoaluminuml complexes were also used to catalyze the Meerwein–Ponndorf–Verley (MPV) reaction of a series of aromatic and aliphatic aldehydes to the corresponding alcohols.
