An M-NHC catalyst, in which M represents Pd or Pt and NHC represents an N-heterocyclic carbene group, including at least one M atom linked to at least one N-heterocyclic carbene ligand, and the method of using the M-NHC catalyst for selectively preparing oxalates or oxamides, from carbon monoxide, an oxidant, in particular molecular oxygen or air, and an alcohol or an amine respectively, optionally in the presence of a promoter.

The present invention refers to processes for preparing catalyst loaded polyphenylene particles, the so-obtained polyphenylene particles and their use as catalysts.

A method for coupling an alkane with an alkene using a hydrogen transfer catalyst and an alkene dimerization catalyst to form one or more higher molecular weight hydrocarbons.

The present invention relates to methods of employing a metal-organic framework (MOF) as a catalyst for cleaving chemical bonds. In particular instances, the MOF results in selective bond cleavage that results in hydrogenolyzis. Furthermore, the MOF catalyst can be reused in multiple cycles. Such MOF-based catalysts can be useful, e.g., to convert biomass components.

In one aspect, there is provided a method of coupling a first aromatic compound having a fluorosulfonate substituent to a second aromatic compound having a boron-containing substituent. In another aspect, there is provided a method of coupling a first aromatic compound having a hydroxyl substituent to a second aromatic compound having a boron-containing substituent in a one-pot reaction.

A method for coupling an alkane with an alkene using a hydrogen transfer catalyst and an alkene dimerization catalyst to form one or more higher molecular weight hydrocarbons.

The invention provides a method of alkene metathesis comprising contacting at least a first alkene, which is cardanol and/or anacardic acid, with an alkylidene ruthenium alkene metathesis catalyst comprising two ligands P.sup.1 and P.sup.2, which may be the same or different and of formula P(R.sup.1).sup.3, in which P is a phosphorus atom coordinated to the ruthenium ion and each R.sup.1 is independently an optionally substituted alkyl or alkoxy group; or two R.sup.1 groups within one P.sup.1 or P.sup.2 ligand constitute an optionally substituted bicycloalkyl.

A radio access network (RAN) configured to support real-time communications over a Long-Term Evolution (LTE) connection is described herein. When a request for a data transmission is received and a real-time communication session over the LTE connection is established, the RAN utilizes the LTE connection, not a New Radio (NR) connection, for the data transmission. When a request for a further real-time communication is received and there is an active data transmission session over the NR connection, the RAN performs at least one of ceasing to allocate traffic to the NR connection for downlink or reconfiguring the data transmission session to send data over the LTE connection.

The invention concerns the ruthenium complexes of the formula 1: ##STR00001##
acting as pre(catalysts) in the reaction of metathesis of olefins, as well as a method for their production, and their usage.

The present disclosure provides a series of new and improved porous polyamide aerogels derived from multifunctional aromatics that combine the high mechanical strength of aramids with the pore structure of aerogels. The polyamide aerogels have a hyperbranched structure, relatively low density, high porosity and may be derived from functionalized monomers having more aromatic groups than functional groups. The present disclosure also provides a new method for producing the porous polyamide aerogels by polymerizing an aromatic multifunctional carboxylic acid or a ferrocene multifunctional carboxylic acid with a polyfunctional aromatic isocyanate at moderate reaction conditions followed by drying with liquid CO.sub.2. Also disclosed are various methods of use of these polyamide aerogels in a variety of applications, particularly in the generation of various precious metal catalysts. Thus, monolithic nanoporous carbon-supported Fe, Au, Pt, Pd, Co, Ni, Ru, and Rh catalysts are disclosed herein, which are derived by pyrolysis and transmetalation via galvanic replacement of ferrocene-based polyamide aerogels.
