• 論文の詳細を見る

• Aqueous organic two-phase reactions (halogen exchange, cyanation, and borohydride reduction) have been catalyzed by phosphoric triamides containing hydrophobic groups. The phosphoric triamides, which have a high cation binding ability, exibited high catalytic activity for the two-phase reactions. The catalytic activity of <I>N</I>-alkylteramethylphosphoric triamides (<B>1</B>) was higher than that of the corresponding pentamethyl derivatives and the difference has been explained in terms of the contribution of the dimeric species of <B>1</B> and/or hydrogen bonding between the NH of <B>1</B> and the anionic moieties of inorganic reagents.
