ABSTRACT:
Aryl phosphinites of the formula (I) ##STR1## can be prepared in a simple manner and in high yields by reacting 2,4-di-tert.-butylphenylphosphonous dihalides with alkyl- or arylmagnesium bromides or alkyl- or arylmagnesium chlorides.
Aryl phosphinites serve for the preparation of secondary phosphine oxides which are used as starting materials for the preparation of phosphine ligands in catalyst systems.
