Applications. Various N-derivatives of amino acids (qv) are resolvable on BSA columns. These A/-amino acid derivatives include benzenesulfonyl-, phthalimido-, 5-dimethylamino-l-naphthalenesulfonyl- (DANSYL-), 2,4-dinitrophenyl- (DNP-), and 2,3,6-trinitrophenyl- (TNP-) derivatives (30). Amines such as Prilocain, (+)-2-(propylamino)-0-propiono-toluidide, a local anesthetic (Astra Pharm. Co.), are also resolved on BSA. The aromatic amino acids DL-tryptophan, 5-hydroxy-DL-tryptophan, DL-kynurenine [343-65-7], C10H12N2O3, and 3-hydroxy-m.-kynurenine [484-78-6], and dmgs such as warfarin, phenprocoumon, and benzodiazepine derivatives can be separated on BSA as well.

In sharp contrast to the coupling of the l,2-bis(diisopropylamino)-3-lithiocyclopropenylium ion 10 with the chlorocyclopropenylium ion containing rather bulky alkylamino substituents, the reaction with the 3-chloro-l,2-bis(dimethylamino)cyclopropenyliuin ion 18 took a completely different course i.c. a nucleophilic attack at the amino-substituted carbon of the chlorocyclopropenylium ring, a ring cleavage, then a second nucleophilic attack at the other amino-substituted carbon, followed by protonation. The whole reaction afforded the 1,3-bis-[2,3-bis(diisopropylamino)cyclopropenyliumyl]-l,3-bis(dimethylamino)propenylium trication 20 142 Trication 20 was also prepared by the reaction of two equivalents of l,2-bis(diiso-propylamino)-3-lithiocyclopropenylium perchlorate (10) with l,3-dichloro-l,3-bis(dimethyl-amino)allyl cation 19.
