nyl-, succinyl-, and terephthalo-dihydrazone complexes were studied in homogeneous oxidation processes of various aliphatic and cyclic alkenes using aqueous H2O2 or TBHP (tert-butyl hydroperoxide) as a terminal oxidant. The catalytic potentiality is quantitative and highly selective to afford the corresponding oxide product with MoVIO2 complexes which is 5 times more than that with UVIO2 complexes
摘要在各种脂肪族和环状烯烃的均相氧化过程中,研究了二氧
钼(VI)和二氧
铀(VI)均双
金属双-ONO三齿(2-羟基-1-亚苄基)丙二酰,琥珀酰和对苯二di配合物的催化势。使用H 2 O 2
水溶液或
TBHP(
叔丁基过氧化氢)作为末端氧化剂。催化潜力是定量的,并且具有很高的选择性,可提供相应的氧化物产物与Mo VI O 2络合物,比使用H 2 O 2
水溶液的U VI O 2络合物高5倍。或
TBHP。在含
