pyridine nitrogen and oxygen in hydroxyl of 8‐hydroxyquinoline coordinated with Mo atom. The crystal catalyst was stabilized by π‐π stacking interaction and hydrogen bonds to form isolated Mo specie. The single‐site molybdenumcatalyst exhibited excellent catalytic performance in didehydroxylation reactions with highselectively of dibutyl fumarate (86 %) product at mild reaction condition.

molecule was developed, where the polarization and the singlet state were preserved over two controlled chemical steps. Nuclear singlet‐state lifetimes close to 6 min for protons are reported in dimethylfumarate. Owing to the high symmetry (AA′X3X3′ and A2 systems), the singlet‐state readout requires either a chemical desymmetrization or a long and repeated spin lock. Using DFT calculations and relaxation
开发了超极化分子的合成,其中在两个受控化学步骤中保留了极化和单重态。据报道,富马酸二甲酯的质子核单重态寿命接近6分钟。由于具有高对称性(AA'X 3 X 3 '和A 2系统),单重态读数需要化学去对称或长时间重复的自旋锁定。使用DFT计算和弛豫模型,我们进一步确定核自旋单重态寿命的限制因素,包括分子内偶极耦合机制(质子-质子和质子-氘),化学位移各向异性机制(对称和反对称)以及分子间偶极耦合机理(氧和氘)。如果可以消除由残余氧引起的顺磁弛豫的限制,则分子内偶极与氘的偶合将成为限制弛豫机制,并且此处考虑的分子(马来酸二甲酯和富马酸二甲酯)的质子寿命可以达到26分钟。
