More specifically, the present invention is directed to catalysts for electroless metallization containing five-membered heterocyclic nitrogen compounds which are stable during storage and electroless metallization.Conventional printed circuit boards (PCBs) consist of laminated non-conductive dielectric substrates that rely on drilled and plated through holes (PTHs) to form a connection between the opposite sides and/or inner layers of a board. Electroless plating is a well-known process for preparing metallic coatings on surfaces. Electroless plating of a dielectric surface requires the prior deposition of a catalyst. The most commonly used method to catalyze or activate laminated non-conductive dielectric substrate regions, prior to electroless plating, is to treat the board with an aqueous tin-palladium colloid in an acidic chloride medium. The colloid consists of a metallic palladium core surrounded by a stabilizing layer of tin(II) ions. A shell of [SnCl] complexes act as surface stabilizing groups to avoid agglomeration of colloids in suspension.In the activation process, the palladium ...

CATALYST AND BATTERY COMPONENTS DERIVED FROM CONDENSATION REACTIONS WITH CARBA-CLOSO-DODECABORATE AMINES

Номер: US20170084954A1
Принадлежит:

Described herein is the fusion of two families of unique carbon-containing molecules that readily disregard the tendency of carbon to form four chemical bonds, namely N-heterocyclic carbenes (NHCs) and carborane anions. Deprotonation of an anionic imidazolium salt with lithium diisopropylamide at room temperature leads to a mixture of lithium complexes of C-2 and C-5 dianionic NHC constitutional isomers as well as a trianionic (C-2, C-5) adduct. Judicious choice of the base and reaction conditions allows for the selective formation of all three stable polyanionic carbenes. In solution, the so-called abnormal C-5 NHC lithium complex slowly isomerizes to the normal C-2 NHC, and the process can be proton catalyzed by the addition of the anionic imidazolium salt. These results indicate that the combination of two unusual forms of carbon atoms can lead to unexpected chemical behavior, and that this strategy paves the way for the development of a broad new generation of NHC ligands for catalysis. 2.
