Addition of boranes to N-aryl-salicylaldimines takes place initially at the reactive phenolic O-H bond to give an activated boron-containing imine and dihydrogen. In some cases a subsequent intramolecular hydrogenation step is observed and the CN imine bond is reduced to the corresponding amine. Reactions with dimesitylborane in THF are unique in that the reduced amine product is the major product observed in solution.

Reactions in 1:1 molar ratio of 2-isopropoxy-4, 4, 5, 5tetramethyl-1, 3, 2-dioxaborolane with N-arylsali-cylaldimines (LH=HOC6 H4CH=NC6H5, HOC6H4CH=NC6H4Me2-2,6, HOC6H4CH=NC6H2Me3-2,4,6, HOC6H4CH=NC6H3Et2-2, 6, and HOC6H4CH=NC6H3Pr2-2, 6 in benzene afford new cyclic compounds of boron containing pinacolate and salicylaldiminate groups. These new derivatives have been characterized by elemental analysis and spectroscopic [IR, NMR (1H, 13C, and 11B)] studies as well as by molecular weight determinations.
