Abstract

There has been no successful chelation of any phosphorus-acetylenic or phosphorous-nitrile ligand. The objectives of this study were to synthesize such ligands and to study their chemistry and chelating tendencies. The best choice appeared to be the preparation of ortho-substituted triphenylphosphines similar to the chelating ligand allylphenyldiphenylphosphine. The Grignard reactions utilized in the preparation of the olefinic compound could not be used in most cases due to the high reactivity of the acetylene and nitrile function Bromobenzene and iodobenzene have been reacted with alkali metal phosphines under conditions that were probably too drastic for the acetylenic and nitrile functions. There has been no mention of any similar reaction with a corresponding chloro compound. The high reactivity of sodium and potassium phosphide compounds and the resulting product mixtures indicated that the corresponding reaction with a lithium compound might be more fruitful. It was decided to pursue the reaction of diphenylphosphino lithium with the ortho substituted chlorobenzenes.
