Methods, systems, and apparatus for monitoring and controlling electronic devices using wired and wireless protocols are disclosed. The systems and apparatus may monitor their environment for signals from electronic devices. The systems and apparatus may take and disambiguate the signals that are received from the devices in their environment to identify the devices and associate control signals with the devices. The systems and apparatus may use communication means to send control signals to the identified electronic devices. Multiple apparatuses or systems may be connected together into networks, including mesh networks, to make for a more robust architecture.

Disclosed is an application of an ionic iron (III) complex as a catalyst in preparation of a benzylamine compound, that is, an ionic iron (III) complex having a molecular formula of [(RNCHCHNR)CH][FeBr.sub.4] (R is tert-butyl) and containing 1,3-di-tert-butyl imidazolium cation is used as a catalyst, di-tert-butyl peroxide is used as an oxidizing agent, and a benzylamine compound is synthesized by oxidation reaction of a toluene/ethylbenzene compound with an aromatic amine. The present invention has a wide application range, and is applicable not only to a toluene compound containing a benzylic primary carbon-hydrogen bond but also to an ethylbenzene compound containing a benzyl secondary carbon-hydrogen bond. This is the first example of the preparation of a benzylamine compound by oxidation reaction of a toluene/ethylbenzene compound and an aromatic amine by an iron-based catalyst.

This application pertains to group 5 metal complexes having the structure of Formula I: ##STR00001##
and their potential utility in catalyzing α-alkylation of secondary amine-containing moieties.
