Abstract

The influence of alkyl substituents in 1-alkene substrates in the rhodium-catalysed hydroformylation in the presence of tris (2-tert-butyl-methylphenyl) phosphite has been studied and compared with that observed for the reaction involving the conventional PPh3- modified catalyst. Hindered alkenes underwent hydroformylation at good rates (ie 1300 mol (mol Rh)− 1 h− 1 for 3, 3-dimethyl-1-butene as T= 70° C and P= 20 bar (H2 CO)); under ...
