The Wilkinson Complex as a heterogeneous catalyst in the partial hydrogenation of 1-heptyne. regeneration of the complex
(Sociedade Brasileira de Química, 2016-06)
The Wilkinson complex was tested as a catalyst in the partial hydrogenation of 1-heptyne, a medium chain alkyne, at a temperature of T = 303 K and hydrogen pressure PH2 = 150 kPa. The tests were performed in homogeneous ...

Graphite oxide as a support for palladium and rhodium complexes, assessed as catalysts for the partial hydrogenation of 1-heptyne
(MedCrave, 2020-08)
Graphite oxide (GO) was used to anchor [PdCl2(TDA)2] and [RhCl(TDA)3] (TDA = NH2(CH2)12CH3) with 2wt % of metal load. Elemental analysis (EA), FTIR, XPS, XRD and atomic absorption spectroscopy (AA) were the techniques ...
Kinetics of the homogeneous hydrogenation of avermectins catalyzed by RhCl(Ph3P)3 complexes
(Elsevier Science, 2005-12)
The kinetics of the hydrogenation of avermectins B1a and B1b catalyzed by RhCl(Ph3P)3 complexes was studied in a temperature range of 298–328 K at 275.7 kN m2, using catalyst loading in the range of 0.75–7.25 wt.% with ...
Immobilized Rh, Ru, Pd and Ni complexes as catalysts in the hydrogenation of cyclohexene
(Elsevier Science, 2004-10)
Complexes of Rh, Ru, Pd and Ni with tridecylamine and chloride as ligands were prepared and tested as heterogeneous catalysts for the hydrogenation of cyclohexene. The Wilkinson's complex was used as a reference catalyst. ...
Kinship, association, and social complexity in bats
(2019-01)
Among mammals, bats exhibit extreme variation in sociality, with some species living largely solitary lives while others form colonies of more than a million individuals. Some tropical species form groups during the day ...

Post-pandemic transformations: How and why COVID-19 requires us to re‐ think development
COVID-19 is proving to be the long awaited ‘big one’: a pandemic capable of bringing societies and
economies to their knees. There is an urgent need to examine how COVID-19 – as a health and
development crisis - unfolded ...
