(endo)pinane in the 85–88 % range at near 100 % conversion.With the homogeneous Wilkinson catalyst an 88 % selec-tivity to cis pinane was also observed but only at 82 %conversion. The use of a 1 % Rh/Al2O3catalyst for thishydrogenation gave some unexpected results. There was a...

catalyst allows for an increase in fiber density to above 1.30 in the oxidation process which is completed in a time of about six minutes. Now it is ready for the carbonization step. Void formation in the fibers is prevented by the use of amine catalysts. Other advantages of using the ...
Wilkinson's catalyst is the common name for chlorotris(triphenylphosphine)rhodium(I), a chemical compound with the formula RhCl(PPh3)3 (Ph = phenyl). It is named after the late organometallic chemist and 1973 Nobel Laureate, Sir Geoffrey Wilkinson who popularized its use. The compound is a ...
The results clearly showed the saturation of those reactive functional groups with Wilkinson's catalyst as well as enhanced spin polarizations, which will be a firm basis for developing new types of hydrogenation catalysts in mild conditions. The benchtop NMR system integrated with the use of para...
High yield, low reaction times, use of green solvents and non-toxicity of the catalyst are the main merits of this protocol. Also, magnetic separation is an environmentally friendly alternative for the recovery of the catalyst, since it minimizes energy and catalyst loss by preventing mass...
Production of Wilkinson catalysts and their regeneration from a chemical reaction product (especially a hydrogenation) is effected using triphenylphosphine and the production involves use of a carbonyl derivative of the catalystRegeneration of a Wilkinson catalyst from a product of chemical reaction of ...
