Description

  • General description: Proton-sponge is a nucleophilic base used in alkoxycarbonylation, dehydrofluorination, arylation, and intramolecular cyclization reactions.[1]Proton-sponge is also referred to as 1,8-dimethylamino naphthalene.[2] It is very strong base with weak nucleophilic character due to steric effects.[3] It also participates in the reactions between arachno-6,9-C2B8H14 and selected acyl chlorides.[2] It has been tested as an effective H+ scavenger.[4]
  • Application: 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.[5] It was also used in the preparation of saturated fluoroalkyl(hydrido) complexes of Iridium.[6]
  • Legal Information: Proton-sponge is a registered trademark of Merck KGaA, Darmstadt, Germany
