    Abstract: The present invention provides a catalyst-imparting treatment solution and an electroless plating method that can form a protective film of a phosphorus-containing alloy to protect the surface of copper inter-connects of an electronic device without forming voids in the copper inter-connects. The catalyst-imparting treatment solution, for use in a catalyst-imparting pretreatment before carrying out electroless plating of at least part of an electronic device having an embedded copper-interconnect structure using a hypophosphite as a reducing agent, includes at least one complex compound of a noble metal of Group IB or Group VIII of the Periodic Table.

    Abstract: A dehydrogenation catalyst includes an organometallic pincer complex bonded to a mesoporous inorganic oxide support, the organometallic pincer complex possessing catalytic activity for alkyl group dehydrogenation. The pincer complex includes at least one element selected from Group VIII or Group IB of the Periodic Table of the elements, and at least one element selected from Group VA of the Periodic Table of the elements in each of two molecular arms, the Group VIII or Group IB element being bonded to each of the Group VA elements. The catalyst is advantageously employed in conjunction with catalytic distillation to permit the dehydrogenation of organic compounds at lower temperatures and at lower cost than conventional methods.

    Abstract: A high productivity catalyst for bisphenol-A has been discovered which comprises strongly acidic cation-exchange resin spheres produced from a polystyrene/divinylbenzene (PS/DVB) copolymer sulfonated under conditions to introduce sulfone cross-linking. Surprisingly, the sulfone cross-linking improves the resistance to deformation but does not have a negative effect on the activity and selectivity of the catalyst in bisphenol-A production.
