Boron Derivatives of Benzaldimines and Salicylaldimines

Abstract
Reactions of equimolar amounts of unsymmetrical monoisopropoxyboranes with N-substituted benzaldimines and salicylaldimines have been carried out in benzene as solvent. Most of the resulting benzaldimine derivatives are distillable liquids, whereas those of salicyl-aldimines are solids and appear to be resistant to hydrolysis. All of these have been characterized by elemental analyses, IR, 1H NMR and 11B NMR spectral studies and conductance measurements. Ebullioscopic determinations of molecular weights show that these compounds are monomeric.
