Triphenylphosphine guanidinium-modified

Scheme 5.2-15 Synthesis of a guanidinium-modified triphenylphosphine ligand.

In contrast to the use of PPhs as the ligand, the reaction takes place solely in the ionic liquid layer when the guanidinium-modified triphenylphosphine is applied. In the first catalytic run the hydroformylation activity was found to be somewhat lower thanwithPPhs (probably due to the ct that some ofthe activity observed with PPhs...
