Azomethine derivatives. Part III. Reactions between diphenylketimine and trimethylgallium, triethylgallium, and triphenylgallium

Abstract

Diphenylketimine and trimethylgallium form a crystalline adduct Ph₂C:NH,GaMe₃ which at 100° loses methane to form the azomethine derivative (Ph₂C:N·GaMe₂)₂. In the systems Ph₂C:NH–GaR₃(R = Et or Ph) the 1 : 1 mixtures of the components are viscous liquids whose proton magnetic resonance (p.m.r.) spectra provide evidence of weak complex formation. Both systems lose RH readily at 100–120° to form azomethine derivatives (Ph₂C:N·GaR₂)₂. Features of the infrared, p.m.r., and mass spectra of these compounds are discussed.
