Mechanistic study of Ru-NHC-catalyzed hydrodefluorination of fluoropyridines : the influence of the NHC on the regioselectivity of C–F activation and chemoselectivity of C–F versus C–H bond cleavage
(2015-02-06) - Journal articleWe describe a combined experimental and computational study into the scope, regioselectivity, and mechanism of the catalytic hydrodefluorination (HDF) of fluoropyridines, C5F5?xHxN (x = 0?2), at two Ru(NHC)(PPh3)2(CO)H2 ... -
NHCs in organocatalysis : azolium enolate generation and synthetic applications
(University of St Andrews, 2012-11-30) - ThesisThis thesis details investigations into organocatalytic reactions promoted by N Heterocyclic Carbenes (NHCs) that proceed via an assumed azolium enolate intermediate. Initial research focused on the catalytic asymmetric ... -
The role of silver additives in gold-mediated C-H functionalisation
(2011-07-01) - Journal articleThe role of silver additives is examined in the context of gold-mediated functionalisation of aromatic C-H bonds. Doubt is cast on the commonly cited route of halide abstraction from gold and evidence of substrate activation ... -
Ruthenium indenylidene "1st generation" olefin metathesis catalysts containing triisopropyl phosphite
(2015-09-01) - Journal articleThe reaction of triisopropyl phosphite with phosphine-based indenylidene pre-catalysts affords “1st generation” cis-complexes. These have been used in olefin metathesis reactions. The cis-Ru species exhibit noticeable ...
