A method is disclosed. The method includes receiving transaction data in an authorization request message from an access device, where the transaction data is associated with a merchant and a transaction location. The method also includes analyzing the transaction data to determine if a location database comprises location data corresponding to the merchant associated with the transaction data, and adding the transaction location and information regarding the access device to the location database.

Tripentyl esters of trimellitic acid, especially mixtures of triisopentyl esters of trimellitic acid comprising isomeric pentyl radicals in which more than 5 mol % of the isomeric pentyl radicals incorporated in the ester mixture are branched, have good compatibility with PVC and PVC-containing polymers and simultaneously exhibit a lesser tendency to migrate.

Provided are methods and materials for the functionalization of a heteroalkane or arene using an oxidizing electrophile as a stoichiometric agent or catalyst. The reaction involves the replacement of a hydrogen atom on an sp3-hybridized carbon atom of the heteroalkane or of a hydrogen atom on an sp2-hybridized carbon atom of the arene. A main group element organometallic intermediate is formed that undergoes further conversion to a functionalized heteroalkane or arene.
