alkoxyamines are coupled to a xanthone unit as triplet sensitizer enabling their reversible photodissociation into two radical species. By studying the photochemical properties of three generations of sensitized alkoxyamines it became clear that the nature and efficiency of tripletenergytransfer from the sensitizer to the alkoxyamine bond as well as the reversibility of photodissociation crucially depends

α-Arylalkanoic acids are prepared by a method comprising the step of reacting an alkylaromatic compound corresponding to the desired α-arylalkanoic acid with a new metallation reagent solution. The reagent comprises the reaction product of alkyllithium or aryllithium and about two to five molar equivalents of potassium tert-alkoxide in a trialkylamine solvent.

Disclosed is a method for producing graphene functionalized at its edge positions of graphite. Organic material having one or more functional groups is reacted with graphite in reaction medium comprising methanesulfonic acid and phosphorus pentoxide, or in reaction medium comprising trifluoromethanesulfonic acid, to produce graphene having organic material fuctionalized at edges. And then, high purity and large scaled graphene and film can be obtained by dispersing, centrifugal separating the functionalized graphene in a solvent and reducing, in particular heat treating the graphene. According to the present invention graphene can be produced inexpensively in a large amount with a minimum loss of graphite.
