摘要

The syntheses and stereochemical studies of N-BH3 adducts of trialkyl-1, 3, 5- triazacyclohexanes [1, R= CH3; 2. R= iso-C3H7: 3. R= CH (CH3)(C6H5)(R); 4, R= tert- C4H9] are reported. Different reagent ratios were used in order to obtain mono-and di-N- borane adducts. Tri-N-borane adducts were never observed: di-N-borane adducts were formed with triazine 1 and 2 whereas 3 and 4 afforded only the mono-boranes. It appears ...
