本文研究了过氧酞菁钛(PcTi0_2)在三苯基膦(Ph_3P)以及1-辛烯氧化反应中氧原子转移性能.在温和条件下,PcTiO_2可化学计量地转移一个氧原子至Ph_3P形成Ph_3O.然而,在1-辛烯的氧化反应中,只有在共催化剂,(PhCN)_2PdCl_2存在下,PcTiO_2才能将氧原子转移至被Pd化合物活化的烯烃上形成辛酮.实验结果表明,PcTiO_2在上述两个氧化反应中,只能起转移一个氧原子的作用,不可能形成以分子氧为氧化剂的催化氧化体系. In this paper, the oxygen transfer properties of PcTiO_2 in triphenylphosphine (Ph_3P) and in the oxidation of 1-octene have been investigated. Under mild conditions, PcTiO_2 can stoichiometrically transfer one oxygen atom to Ph_3P to form Ph_3O However, in the oxidation of 1-octene, only the cocatalyst, (PhCN) 2PdCl_2, PcTiO_2 in the oxygen atoms can be activated by the Pd compound to form an octane on the olefin.Experimental results show that, PcTiO_2 in the above Two oxidation reactions, can only play a role in the transfer of an oxygen atom, it is impossible to form a catalytic oxidation system with molecular oxygen as the oxidant.
