Regio- and stereoselective synthesis of enantiomerically pure [60]fullerene tris-adducts with an inherently chiral e,e,e addition pattern
(2005)The synthesis and flash column chromatographic separation of c enantiomerically pure tris-adducts of C60 with an e,e,e-addition pattern is achieved via cyclopropanation with chiral D3-symmetrical cyclo-tris(malonate) ...

Regioselective synthesis and zone selective deprotection of [60]fullerene tris-adducts with an e,e,e addition pattern
(2005)D3h-symmetrical tripodal tris(malonate) tethers have been used for the synthesis of [60]fullerene tris-adducts with an e,e,e addition pattern bearing topologically distinct polar and equatorial addend zones that can ...

Reinvestigating the synthesis of N-arylbenzamidines from benzonitriles and anilines in the presence of AlCl3
(2010)The preparation of N-phenylbenzamidine 3a from the reaction between benzonitrile Ia and aniline in the presence of AId3 is reinvestigated with respect to mode of reagent addition, reaction temperature and Lewis acid ...

Remote functionalization of C60 with enantiomerically pure cyclo-[2]-malonate tethers bearing C12 and C14 spacers: Synthetic access to bisadducts of C60 with the inherently chiral trans-3 addition pattern
(2013)In this Article, we describe the synthesis of two optically pure diols bearing a 1,2-diol moiety masked as an isopropylidene acetal group and long alkyl chains comprised of 12 and 14 carbon atoms, respectively. The synthetic ...

Synthesis, characterization and evaluation of amphiphilic star copolymeric emulsifiers based on methoxy hexa(ethylene glycol) methacrylate and benzyl methacrylate
(2005)Amphiphilic star copolymers were synthesized by sequential monomer and cross-linker additions using group transfer polymerization (GTP). Benzyl methacrylate (BzMA) and methoxy hexa(ethylene glycol) methacrylate (HEGMA) ...
