Fullerene derivatives reaction with amines

Figure 15.9 The reaction of the amine-blocked derivative of 3-hydroxypropylamine with ethylmalonyl chloride gives an ethylmalonate-protected-amine compound, which can be used in the Bingel reaction to create an amine group on a fullerene surface. Reaction with Cfl in the presence of I2 and DBU gives the cyclopropanation product that can be deprotected with TFA to yield the free amine.

Another route to fabricate fullerene doped monoliths has been shown by Peng et al. (2001), which successfully prepared crack free, transparent fullerene glasses oflarge dimensions (up to 60 mm) from sol-gel mixtures of aminated Cgo derivatives and tetraethyl orthosilicate (TEOS). The aminated fullerene derivatives have been synthesized by amination reactions of Ceo with 6-amino-l-hexanol, cyclohexylamine, 2-(2-aminoethoxy)ethanol, and 3-aminopropyltriethoxysilane to prepare derivatives with the molecular structures H C6o[NH(CH2)6oH]jt, H C6o(NH-cyc/o-C6Hn)je, Hjj,C6o[NH(CH2CH2o)2H], and H (C6o[NH(CH2)3Si(OCH2CH3)3]i . A silica network with covalently bonded amine fullerene derivatives has been obtained, as shown in Figure 23-3. [Pg.1682]

Fullerene derivatives occupy a privileged position in chemistry as they have many potential applications in materials and biomolecules. Recently, Wang and You reported a FeClj-catalyzed synthesis of oxazolidino[4,5 l,2] [60]fullerenes via the intermolecular tandem reaction of [60] fullerene with ferf-butyl Af-substituted carbamates to access through the direct amination between the C(sp )-H bonds and the N-H bonds (Scheme 9.5) [7]. [Pg.294]

Figure 15.5 A trityl-protected pyrrolidine derivative of Cgg can be prepared by the reaction of N-trityl-oxazolidinone with a fullerene. Deprotection of the trityl group using methanesulfonic acid gives the secondary amine, which can be used in further conjugation reactions.
