Publication number: 20130123514Abstract: The disclosure relates to catalytically active carbocatalysts, e.g., a graphene oxide or graphite oxide catalyst suitable for use in a variety of chemical transformations. In one embodiment, it relates to a method of catalyzing a chemical reaction of an organic molecule by reacting the organic molecule in the presence of a sufficient amount of graphene oxide or graphite oxide for a time and at a temperature sufficient to allow catalysis of a chemical reaction. According to other embodiments, the reaction may be an oxidation reaction, a hydration reaction, a dehydrogenation reaction, a condensation reaction, or a polymerization reaction. Some reactions may include auto-tandem reactions. The disclosure further provides reaction mixtures containing an organic molecule and graphene oxide or graphite oxide in an amount sufficient to catalyze a reaction of the organic molecule.Type: ApplicationFiled: May 27, 2011Publication date: May 16, 2013Applicant: GRAPHEA, INC.Inventors: Christopher W.

Publication number: 20130105297Abstract: Disclosed is a method for the photoinitiated transformation of a transformable reactive substrate. The method includes an initial step in which a protected ketone photoinitiator species which is present in the substrate is deprotected to form the corresponding ketone photoinitiator species for use in a subsequent photoinitiated reaction in the method. The ketone group of the photoinitiator is protected by an unsubstituted 1, 3 dioxolane group. Also disclosed are a composition which may be used in the method, the use of the protected ketone photoinitiator in a photoinitiated reaction, as well as the protected ketone photoinitiators themselves.Type: ApplicationFiled: January 17, 2011Publication date: May 2, 2013Applicant: LINTFIELD LIMITEDInventors: Robert A.
