分子氮络合物的研究,是近年来极为活跃的一个领域,Chatt等于1975年在室温下成功地将分子氮络合物中的氮分子加质子转变成氨,证明了配位于过渡金属的氮分子的确能被活化并接受质子而生成氨.他们对分子氮络合物的加质子反应进行了详细研究后发现:只有单膦配位的分子氮络合物,如顺式[M(N_2)_2(PMe_2Ph)_4]及反式[M(N_2)_2(PMePh_2)_4](M=Mo或W),在室温下能和硫酸-甲醇作用而生成氨;具有双膦配位的分子氮络合物反式[M(N_2)_2(Ph_2PCH_2CH_2PPh_2)_2](M=Mo或W)则在质子酸作用下只能加质子而得到一系列具有
Molecular nitrogen complex is an extremely active field in recent years. Chatt et al. Succeeded in converting nitrogen molecules and protons in the molecular nitrogen complex to ammonia at room temperature in 1975, and proved that nitrogen coordinated to the transition metal The molecules can indeed be activated and accept protons to generate ammonia. They studied the proton-responsive protonation of molecular nitrogen complexes and found that only mononuclear phosphine-coordinated molecular nitrogen complexes such as cis [M (N 2) (M = N 2) _2 (PMePh_2) _4] (M = Mo or W) can react with sulfuric acid-methanol to generate ammonia at room temperature. The molecular nitrogen network with biphosphine coordination The trans [M (N_2) _2 (Ph_2PCH_2CH_2PPh_2) _2] (M = Mo or W) can only add protons under the action of protonic acid to obtain a series of
