Abstract: This method for changing the radio access point associated with a terminal, within a Wi-Fi-DECT wireless telecommunication network comprising dual-mode Wi-Fi-DECT radio terminals (PP) and Wi-Fi-DECT radio access points (AP1, AP2) connected to a local area network; comprises a step consisting of changing the Wi-Fi-DECT radio access point for the Wi-Fi part of the terminal in question (PP) whenever it is decided to change the Wi-Fi-DECT radio access point for the DECT part of the terminal in question (PP).

They are suitable for the antimicrobial treatment of surfaces, especially as antimicrobial active ingredients against gram-positive and gram-negative bacteria.

Abstract: A process is described for preparing diphenylamines of the formula ##STR1## by oxybromination of a phenol ether compound using elemental bromine in the presence of hydrogen peroxide and of a catalyst to give a brominated phenol ether compound which is subsequently reacted with a formanilide compound to give the compound of the formula (1).The oxybromination reaction is a regioselective, environmentally friendly and cost-efffective method of preparing brominated aromatic compounds.The diphenylamines of the formula (1) are industrially useful intermediates for the production, for example of dyes, and in particular of color formers of the fluoran type for pressure- or heat-sensitive recording systems.
