Lewis Bases

Combination of the Lewis bases Cp2MH2 (where M = W or Mo) with the Group III Lewis acids AlR3 (where R = Me, Et, or Ph) and AlMe2H has yielded a series of 1:1 complexes of the type Cp2MH2•AlR3. A number of the complexes undergoes a slow elimination of hydrogen or alkane in benzene solution. Attempts to isolate mixed hydride adducts of the type, Cp2MH2•M′H3 (where M′ = Al or Ga), were unsuccessful.

Acid Base Interaction

The Lewis acid-base interaction between B(iii) Lewis acids and the pyridazine moiety reduced the electron density from the Ni center and in situ modulated the pyridazine-imine nickel catalyzed ethylene (co)polymerisation.
