    摘要: This invention concerns a new process for the catalytic carbonylation of certain aryl halides or aryl tosylates to amides by use of a complex of palladium and at least one ligand. More specifically, the invention concerns carbonylation of halogenoaromaticsulfonamides or tosylatoaromaticsulfonamides to saccharin, saccharin analogues or their salts.

    摘要: A system and method for converting a message via a posting converter is provided. At least one incoming message is received from a composition device. Characteristics of the message are determined. The characteristics include a target device to which the message is directed and an application through which the message will be presented. An appropriate template is selected for the message based on at least one of the message characteristics. The message is converted to a different format using the selected template. The converted message is provided for display on the target device.
