π Complexes of P^P and P^N chelated gold(i)

Precision measurements of the pp → π + pn and pp → π + d reactions : importance of long - range and tensor force effects

Inclusive measurements of pion production in proton–proton collisions in the forward direction were undertaken at 400 and 600 MeV at COSY using the Big Karl spectrograph. The high resolution in the π momentum ensured that there was an unambiguous separation of the pp → πd/πpn channels. Using these and earlier data, the ratio of the production cross sections could be followed through the ∆ regio...

THE JP = 2+ DIBARYON IN πNN CALCULATION OF pp→π+ pn PROCESS

For pp + $pn reaction at Elab = 400 1000 MeV the theoretical J~ = 2+ amplitude due to the n N N dynamics makes an anticlockwise looping behavior in the Argand plot and provides an evidence in favour for the existence of the J P = 2+ dibaryon. 1 The n N N dynamics So far the question whether the dibaryons exist or not has been controversial among many peaplell-81. Among them the existence of the...

Chiral MOP-phosphonite ligands: synthesis, characterisation and interconversion of η,η-(σ-P, π-arene) chelated rhodium(I) complexes†

Monodentate phosphorus ligands based on the MOP architecture are proven as valuable ligands in asymmetric catalysis. It is widely recognised that these ligands can act as P,arene bidentate chelates to stabilise coordinatively unsaturated electron deficient metal centres. As such, hemilabile arene interactions are anticipated to be present, or indeed imperative, in catalytic processes. Whilst pa...

Chiral MOP-phosphonite ligands: synthesis, characterisation and interconversion of η1,η6-(σ-P, π-arene) chelated rhodium(I) complexes.

The synthesis of rhodium(I) and iridium(I) complexes of chiral MOP-phosphonite ligands is reported. The full characterisation of η(1),η(6)-(σ-P, π-arene) chelated 18VE rhodium(I) complexes reveals hemilabile binding on the arene which has been quantitatively analysed.
