As biomimetic models for the activesite of Fe-onlyhydrogenases,six new N-substituted diiron azadithiolates (ADT) were prepared.Treatment of CH2Cl2 solutions of primary amines RNH2 with paraformaldehyde followed by an excess of SOCl2 gave N,N-bis(chloromethyl)amines RN(CH2Cl)2 (1,R = CH2CO2Et;2,C6H4C(O)Me-p;3,C6H4CO2Me-p;4,C6H4SCN-p) in 30–90% yields.Further treatment of the chloromethylated amines
作为仅铁化氢酶活性位点的仿生模型,制备了六种新的N-取代的二硫杂二硫杂铁二磺酸盐(ADT),先用多聚甲醛处理伯胺RNH 2的CH 2 Cl 2溶液,再用过量的SOCl 2处理,得到N,N-双(氯甲基)胺RN(CH 2 Cl)2(1,R = CH 2 CO 2 Et; 2,C 6 H 4 C(O)Me- p ; 3,C 6 H 4 CO 2 Me-p ; 4,C 6 H ^ 4 SCN- p)在30-90%的产率的氯甲基化胺的进一步治疗。1 - 4与(μ -LiS)2的Fe 2(CO)6的THF导致形成相应的Ñ取代ADT型模型[(μ- SCH 2)2 NR]的Fe 2(CO)6(5,R = CH 2 CO 2的Et; 6,C 6 H ^ 4 C(O)ME- p; 7,C 6 H 4 CO 2 Me- p;m / z 。8,C 6 H 4 SCN- p)的产率为24-75%。还制备了N-取代的模型[(μ-
