  • Patent number: 10995056
    Abstract: In some aspects, the present disclosure provides methods of aminating an aromatic compound comprising reacting an aminating agent with an aromatic compound in the presence of a rhodium catalyst. In some embodiments, the methods may comprise aminating an aromatic compound which contains multiple different functional groups. The methods described herein may also be used to create bicyclic system comprising reacting an intramolecular aminating agent with an aromatic ring to obtain a second ring containing a nitrogen atom. In another aspect, the methods described herein may also be used to create a cyclic aliphatic cyclic/poly cyclic amine system comprising a reacting an intramolecular aminating agent by insertion into a C(sp3)-H bond.

  • Patent number: 4949075
    Abstract: A portable optical alarm system for area protection containing at least one light-emitting transmitter and a receiver sensing the emitted light is disclosed. The transmitters and receivers of the system form a chain in such a manner that the receiver sensing the light-impulses of the first transmitter is always connected electrically to the following transmitter and the last receiver of the system is connected electrically to the intervening organ and partly to the first transmitter of the system, or the first transmitter of the system is formed as a free-running unit. Transmitters and receivers can be arranged in an optical mutual arrangement where they are arranged in a casing containing the transmitter circuit and the associated battery along with the receiver circuit and the battery belonging thereto.
