Efficient catalyst for the formation of polyaryl hydrocarbons suitable as precursors for polydentate organophosphorus catalyst ligands |
| abstract |
The disclosure relates to the efficient preparation of aromatic hydrocarbons useful as intermediates for di-, tri-, tetra- and poly-dentate organophosphorus ligands having value in particular as hydroformylation catalysts. The use of triarylphosphine halide catalysts have been found to be more efficient in forming these intermediates by the use of excess triarylphosphine in an amount beyond what is required to form a coordination complex. |
