The C 3 vanadium(V) amine triphenolate complex 1f has been characterized as a structural and functionalmodel of vanadiumhaloperoxidases. The complex catalyzes efficiently sulfoxidations at room temperature using hydrogen peroxide as the terminal oxidant, yielding the corresponding sulfoxides in quantitative yields and high selectivities (catalyst loading down to 0.01%, TONs up to 9900, and TOFs up
C 3钒(V)胺三酚盐络合物1f已被表征为钒卤代过氧化物酶的结构和功能模型。该配合物在室温下使用过氧化氢作为末端氧化剂可有效催化亚硫酸盐氧化,以定量收率和高选择性产生相应的亚砜(催化剂负载量低至0.01%,TONs高达9900,TOFs高达8000 h(-1))以及1,3,5-三甲氧基苯的溴化(催化剂负载量低至0.05%,TONs最高可达1260,TOF最高可达220 h(-1))。
