  用于不饱和含氮化合物加氢的高活性无金属催化剂

  摘要：

  通过调节胺部分的碱度和空间体积，制备了用于亚胺直接无金属加氢的新型高活性ansa-硼酸铵催化剂。在先前报道的有机催化体系中，对于各种含氮底物显示出最高的催化活性。演示了基于ansa-硼酸铵概念的不对称亚胺加氢的第一个例子。此外，还阐述了通过用有机溶剂萃取酸性溶液，然后用TMSBr脱水来有效回收催化剂的方法。最初的发现强调了对映选择性氢化更有效的手性ansa-硼酸铵的开发。因此，在Ansa-硼酸铵的概念使其有希望进一步精加工，以期获得工业上适用的催化剂。

  palladium‐catalyzed CH arylation of aliphatic amines with arylboronic esters is described, proceeding through a four‐membered‐ring cyclopalladation pathway. Crucial to the successful outcome of this reaction is the action of an amino‐acid‐derived ligand. A range of hindered secondary amines and arylboronic esters are compatible with this process and the products of the arylation can be advanced to

  We have developed a new synthesis of 3,4-disubstituted-1,2,5-thiadiazoles. The methodology is based on the ring opening of readily available 3,4-dichloro-1,2,5-thiadiazole with metal amides to afford a stable synthon, which is then transformed into the 3,4-disubstituted-1,2,5-thiadiazole derivatives via two consecutive reactions with O-, S-, N- or C-nucleophiles.

  An essentially single stage reaction has been discovered in which a disubstituted ethanolamine, that is, a 2,2'-substituted-2-aminoethanol, may be reacted with a haloform and a carbonyl containing compound selected from the group consisting of monoketones and benzaldehyde, in the presence of an alkali metal hydroxide, and optionally in the presence of a phase transfer catalyst, to produce an alkali metal hydroxyethylaminoacetate ("HEAA") which has N-adjacent C atoms on which there are a total of at least three substituents (hence "polysubstituted"), and one or both pairs of substituents on each N-adjacent C atom may be cyclized. The HEAA may be cyclized by the action of a mineral acid to produce a 2-morpholone hydrochloride which is characterized by having a total of at least three substituents on the N-adjacent C atoms of the ring. The 2-morpholone so produced may be reduced to a polysubstituted aminodiol. The aminodiol so produced may be cyclized with an alkane sulfonic acid to yield a polysubstituted morpholine which could not otherwise have been made. The aminodiol may also be alkylated to produce diethers with polysubstituted N-adjacent C atoms. If the aminodiol is tosylated, a polysubstituted crown ether is produced with plural polyalkylene groups. The foregoing HEAA and related compounds are used as u-v light stabilizers in novel compositions in which a small but effective amount of one or more of the HEAA and related compounds is incorporated, in an amount sufficient to produce desirable stabilization against degradation by u-v light in a wide variety of organic materials.

  发现了一种基本上的单步反应，其中二取代的乙醇胺，即2,2'-取代的-2-氨基乙醇，可以与卤仿和选自单酮和苯甲醛的含羰基化合物在碱金属氢氧化物存在下反应，并可选择性地在相转移催化剂存在下反应，以产生具有N-相邻C原子上的至少三个取代基（因此称为“多取代”）的碱金属羟乙基氨基乙酸酯（“HEAA”），并且每个N-相邻C原子上的一个或两个取代基对可以环化。HEAA可以通过无机酸的作用环化，产生具有环的N-相邻C原子上的至少三个取代基的2-吗啉酮盐酸盐。产生的2-吗啉酮可以被还原为多取代的氨基二醇。产生的氨基二醇可以通过与烷基磺酸反应环化，产生不能通过其他方式制备的多取代吗啉。氨基二醇也可以被烷基化，产生具有多取代N-相邻C原子的二醚。如果氨基二醇被对甲苯磺酰化，会产生具有多个聚亚烷基基团的多取代冠醚。上述HEAA及其相关化合物被用作新型组合物中的紫外线稳定剂，其中包含一种或多种HEAA及其相关化合物的小而有效的量，足以在各种有机材料中产生对抗紫外线降解的理想稳定性。
