摘要
The synthesis, crystal structure and variable temperature magnetic measurements of a new dinuclear Fe(III) complex, [Fe-2(mu(1,3)-O(2)Cfn)(OH2)(MeOH)Cl2L] (1) [fn = furan, L = N,N'-bis(salicyaldehydene)-1,3-diaminopropan-2-ol], is reported. From X-ray diffractometry, it is shown that each Fe(III) centre in I is in a distorted octahedral environment. A variable temperature magnetic study reveals strong antiferromagnetic behaviour of 1 with J = -22.2 +/- 0.1 cm(-1). Use of 1 as an alkene epoxidation catalyst towards (E)-stilbene and styrene with tert-butyl hydrogen peroxide (TBHP) and iodosylbenzene (PhIO) reveals that TBHP is the better oxidant in terms of the yield of the reaction.
