12-trimethyl-1-oxa-4,8,12-triazacyclotetradecane; see picture) in an N3O environment exhibits drastically enhanced reactivity relative to the [FeIV(O)(TMC)(CH3CN)]2+ (TMC=1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane) complex in an N4 environment. This explains nature's preference for using oxygen-rich ligand environments for the hydroxylation of strong C−H bonds.
N中[Fe IV(O)(TMCO)(OTf)] +(TMCO = 4,8,12-三甲基-1-oxa-4,8,12-三氮杂环十四烷;参见图片)中的氧代铁(IV)中心相对于[Fe IV(O)(TMC)(CH 3 CN)] 2+(TMC = 1,4,8,11-四甲基-1,4,8,11-四氮杂环十四烷),3 O环境展现出显着增强的反应性在N 4环境中复杂。这解释了自然界对使用富含氧的配体环境进行强CH键羟基化的偏好。
