Homogeneous perdehydrogenation of saturated bicyclic 2,6-dimethyldecahydro-1,5-naphthyridine and perhydrogenation of aromatic 2,6-dimethyl-1,5-naphthyridine with release and uptake of five molecules of H2 are efficiently achieved by iridium complexes bearing a functional bipyridonate ligand. Successive perhydrogenation and perdehydrogenation of 2,6-dimethyl-1,5-naphthryridine using a single iridium complex also proceed with the reversible interconversion of the catalytic species, depending on the presence or absence of H2.
铱配合物负载功能化双吡啶酮配体可高效实现饱和双环 2,6-二甲基十氢-1,5-萘啶的均相脱氢和芳香 2,6-二甲基-1,5-萘啶的全氢饱和,同时伴随着 5 个 H2 的释放和吸收。使用单个铱配合物对 2,6-二甲基-1,5-萘啶进行连续全氢饱和和脱氢也可进行,这取决于 H2 的存在与否,催化物种的可逆转化也随之发生。
