Preparation of Dioxygen Bridged Palladium Complexes by Superoxide Ion (O2-)

초과산화이온 (O2-) 에 의한 산소가교팔라듐착화합물의 합성
Pyeong Jin Chung

초과산화이온(O2-)의 발생원으로서 KNO2를 사용하여 새로운 형태의 산착화합물가교팔라듐착화합물을 합성했다. 이 방법은 구핵치환과 전자 이동에 의한 반응으로서, 저원자가전이금속착화합물에 산소분자를 산화적으로 부가시켜 합성한 종전의 방법과는 완전히 다르다. O2-에 의하여 π-알릴리간드를 갖는 새로운 형태의 5가지 산소가교팔라듐착화합물을 합성했다.

New type dioxygen bridged complexes of palladium were prepared by using KO2 as a source of superoxide ion (O2-). The method is completely different from the traditional one which has adopted the oxidative addition of molecular oxygen to transition metal complexes in low valency. It was suggested that the reaction to prepare the dioxygen complexes proceeded via nucleophilic displacement followed by electron transfer reaction. Five new type dioxygen complexes having π-allyl ligand were prepared and characterized by the application of the reaction of O2-.
