Methods, systems, and apparatus for monitoring and controlling electronic devices through the use of wired and wireless protocols. The systems and apparatuses may monitor their environment for signals from electronic devices. They may then take and disambiguate the signals that are received from the devices in their environment in order to identify said devices and associate control signals with them. The systems and apparatuses may then use communication means to send control signals to the identified electronic devices. Input and output transmission means for the systems and apparatuses may include, but are not limited to, powerline communication, Wi-Fi, Bluetooth, ZigBee, and 6LoWPAN. Signal processing and device identification may be done onboard the device, or may be done at a remote location. Multiple apparatuses or systems may be connected together into networks, including mesh networks, in order to make for a more robust architecture.

A method for the selective synthesis of a tail-to-head, or a head-to-head, or a tail-to-tail telomer from an unsymmetrical diene by polymerizing the diene in the presence of [Pd(C.sub.3H.sub.5)COD]BF.sub.4 and dicyclohexyl-[1-(2,4,6-trimethylphenyl)imidazol-2-yl]phosphane, Pd(OAc).sub.2 and triphenylphosphine, or [Pd(C.sub.3H.sub.5)COD]BF.sub.4 and tris(2,4-di-tert-butylphenyl)phosphite in combination with a polar protic alcohol, an acidic polar protic alcohol, a polar aprotic ether, or a non-polar aprotic hydrocarbon is provided.
