产品介绍：介绍质子海绵也就是1,8-双二甲氨基萘。因为空间位阻效应，它是一种有亲核性的强碱。它还参与蛛网形-6,9-C2B8H14和选择酰氯的反应。它还是一种有效的H+清除剂。用途由于空间位阻效应而具有弱亲核性的强碱。质子海绵可以用来合成C-取代t-BuNH-8,9-R,R′-nido-7,8,9-C3B8H9 (R,R′=H,H; MeH; Me,Me; Ph,H 和Ph,Ph)三碳内酯化合物。它还可以用来制备饱和铱氟烷基（氢化物）复合体。1,8-Bis(dimethylamino)naphthalene is a very strong base with weak nucleophilic character due to steric effects.Proton-sponge can be 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.
