Publication number: 20130035494Abstract: The invention relates to a method for preparation of ruthenium-based carbene catalysts with chelating alkylidene ligands (so-called “Hoveyda-type catalysts”) in a cross metathesis reaction by reacting a ruthenium-alkylidene complex with an olefin derivate in the presence of a polymer-supported cation-exchange resin (PSR) acting as a ligand (i.e. phosphine or amine) scavenger. Preferably, penta-coordinated ruthenium benzylidene or indenylidene carbene complexes are employed. The polymer-supported cation-exchange resin (PSR) may be an acidic resin (comprising sulfonic acid or carboxylic groups) or a resin containing carboxylic acid chloride (—COCl) groups or sulfonyl chloride (—SO2Cl) groups. The process is versatile and environmentally friendly; high yields are obtained.Type: ApplicationFiled: January 25, 2011Publication date: February 7, 2013Applicants: GHENT UNIVERSITY, UMICORE AG & CO.

Publication number: 20130035322Abstract: Gold (I) hydroxide complexes of the form Z-Au-OH and digold complexes of the form Z—Au-(?OH)—Au—Z where groups Z are two electron donors are provided. The groups Z may be carbenes, for example nitrogen containing heterocyclic carbenes (NHCs), phosphines or phosphites. The complexes can be used as catalysts, for example in reactions such as hydration of nitriles, skeletal arrangement of enynes, alkoxycyclisation of enynes, alkyne hydration, the Meyer-Shuster reaction, 3,3? rearrangement of allylic acetates, cyclisation of propargylic acetates, Beckman rearrangements and hydroamination. The complexes can be used in medicine, for example in the treatment of cancer.Type: ApplicationFiled: March 2, 2011Publication date: February 7, 2013Applicant: University Court of The University of St. AndrewsInventor: Steven P.
