Tanaka, Koichi,Otani, Ken-Ichi,Murase, Takanori,Nishihote, Shyota,Urbanczyk-Lipkowska, Zofia
, p. 709 - 714 (2012)
Two new copper metal-organic frameworks containing 2,2′-dihydroxy-1, 1′-binaphthalene-5,5′-dicarboxylic acid (5,5′-H 2BDA) and 2,2′-dihydroxy-1,1′-binaphthalene-4,4′- dicarboxylic acid (4,4′-H2BDA) have been prepared. X-ray structure determination of [Cu2(5,5′-BDA)2(H 2O)2]·MeOH·2H2O (MOF-1) and [Cu2(4,4′-BDA)2(H2O)2] ·4H2O (MOF-2) revealed similar 2D sheet structures, containing square-grid coordination networks, but differences in the stacking motif. The desolvated MOF-1 and -2 were used as Lewis acid catalysts in the asymmetric ring-opening reaction of epoxides with MeOH.
Graphene oxide as an acid catalyst for the room temperature ring opening of epoxides
Dhakshinamoorthy, Amarajothi,Alvaro, Mercedes,Concepcion, Patricia,Fornes, Vicente,Garcia, Hermenegildo
supporting information; experimental part, p. 5443 - 5445 (2012/07/28)
The minute amount of hydrogen sulfate groups introduced into the graphene oxide (GO) obtained by Hummers oxidation of graphite renders this material as a highly efficient, recyclable acid catalyst for the ring opening of epoxides with methanol and other primary alcohols as nucleophile and solvent.
Sodium borohydride and vinyl triflates of α-keto esters: A new combination toward monoalkylated 1,2-diols
Dalla, Vincent,Decroix, Bernard
, p. 1657 - 1660 (2007/10/03)
NaBH4 converts a range of methyl 2-trifluoromethanesulfonyloxy 3-substituted propenoates to the corresponding monoalkylated 1,2-diols smoothly with total regiocontrol.
