Applicazioni

1,8-Bis(dimethylamino)naphthalene is used in the synthesis of C-substituted t-BuNH-8,9-R,R?-nido-7,8,9-C3B8H9 (R,R? = H,H; MeH; Me,Me; Ph,H and Ph,Ph) tricarbollide compounds. It was also used in the preparation of saturated fluoroalkyl(hydrido) complexes of Iridium.

Note

Air & Light Sensitive. Keep container tightly closed. Store in cool, dry conditions in well sealed containers.

The steric strain is relieved on protonation, hence it is one of the strongest organic bases known, but is only weakly nucleophilic: Chem. Commun., 723 (1968). In DMF vic-dibromides are debrominated in high yield: Synth. Commun., 5, 87 (1975).

Has been used In combination with Diphenyl­phosphonic azide, A12124, for the conversion of carboxylic acids to isocyanates: Synth. Commun., 23, 335 (1993). Preferred base for the conversion of aliphatic amines to isocyanates with Trichloromethyl­ chloroformate, A17444.
