C–C coupling reactions using a gold(iii) phosphorus complex confined within metal–organic framework fibers in aqueous solution

“…and Hiyama [15][16][17] reactions, in the Larock heteroannulation reaction, [18][19][20][21] for the degradation of pollutants, 22 for hydrogenation 23 and in fuel cells. 24 In recent years, it has been proven that the use of complex functional groups, either graed or smeared onto solid supports, plays an important role in preventing the aggregation of metal catalysts.…”

Cyclometalated gold(III) iminophosphoranes which incorporate carbohydrate groups

“…There are a large number of C,N-cyclometalated gold(III) dichloride compounds [12]. The strength of the goldenitrogen bond can be gauged by reaction with various reagents to see if it is a goldechloride or the goldenitrogen bond that is broken; PPh 3 has been used to test this [12].…”

“…The strength of the goldenitrogen bond can be gauged by reaction with various reagents to see if it is a goldechloride or the goldenitrogen bond that is broken; PPh 3 has been used to test this [12]. Scheme 4 shows the two possible pathways; either one of the chlorides is displaced to form a cation or the nitrogen is displaced to form a neutral compound.…”

“…However their use as ligands has not been investigated. Since other gold(III) iminophosphoranes have been shown to be catalytically and biologically active [12], the introduction of a carbohydrate moiety is interesting, since carbohydrates not only introduce chirality but can enhance biological activity as well. This paper reports the synthesis and characterisation of some novel cycloaurated iminophosphoranes.…”

Heterolytic CH-bond activation in the synthesis of Ni{(2-aryl-κC2)pyridine-κN}2 and derivatives

“…Metal-aryl bonds can be entrained within chelates to add kinetic stability, and heterolytic CH-bond activation was considered as an efficient means to synthesize complexes containing such ligands [3][4][5]. There are various approaches to the synthesis of metal-carbon bonds, the most common being metathesis and oxidative addition (OA) [6,7].…”
