标题:尿酸盐作为二碘化mar活化剂的用途
摘要:已经开发了使用尿酸盐作为反应促进剂的smi 2活化的新模式.已经显示出通过用正丁基锂处理相应的脲而形成的几种脲酸酯在很大程度上活化了smi 2,从而还原了1-氯癸烷.由smi 2和各种脲酸酯形成的络合物已显示可用于减少各种有机卤化物,包括低反应性的底物,如芳基氟化物.由于易于合成且分子量低,因此,三乙基脲的共轭碱(teu-)成为主要关注对象.可见光谱和反应性数据与以下假设相符:在smi 2时会形成相同的络合物被结合的teu 2或4当量-,尽管smi的更大反应性的2 /4 Teu-一些烷基卤.我们认为活性还原剂是smi 2和2当量teu-之间形成的n,O螯合物.

标 题:Synthesis of alpha-alkoxycarboxylic acids
发明人：LAI JOHN T
权利人:GOODRICH CO B F
摘要:Numerous alpha-carboxylic acids are prepared in a liquid medium by the reaction of an organic compound having at least one reactive hydroxyl or thiol group, with a monoketone, and a haloform, in the presence of a phase transfer catalyst and an alkali metal hydroxide. The term 'alpha-alkoxycarboxylic acids' includes alpha-phenoxycarboxylic acids, alpha-thioalkoxycarboxylic acids and alpha-thiophenoxycarboxylic acids. Specific substituents on the beta carbon atom of an alpha-alkoxycarboxylic (or '2-alkoxycarboxylic') acid reaction product formed in this novel synthesis, are introduced by appropriate choice of the ketone reactant; alkoxy and phenoxy substituents on the alpha carbon atom of a 2-alkoxycarboxylic acid are introduced by appropriate choice of the organic compound having a hydroxyl or thiol group. De-alkoxylation of the 2-alkoxycarboxylic acid yields alpha-beta monoolefinically unsaturated carboxylic acids which are necessarily alpha substituted, and may also be beta-substituted. It is now possible to produce, simply and conveniently, numerous substituted alpha-beta monolefinically unsaturated carboxylic acids with a variety of substituents on the alpha carbon atom, and, optionally on the beta carbon atom of these substituted carboxylic acids. Esters may also be conventionally derived from both the 2-alkoxycarboxylic acids, and the unsaturated carboxylic acids. During the phase transfer catalyzed synthesis of this invention, an intermediate acyl halide derivative is formed prior to the formation of the 2-alkoxycarboxylic acid reaction product. The formation of the acyl halide derivative allows the subsequent direct formation, in a modification of the same reaction, of 2-alkoxycarboxylic acid amides (or '2-alkoxycarbamides'), simply by adding a primary or secondary amine to the reaction mass. By dealkoxylation of the 2-alkoxycarbamides, specific, necessarily alpha-substituted and optionally beta-substituted acrylamides are synthesized which previously could be prepared, if at all, only with difficulty.

标 题 :Synthesis of N,N-disubstituted-p-phenylenediamine

摘要:An improved synthesis of N,N,-disubstituted-p-phenylene-diamine (DSPDA) preferably di-n-butyl-p-phenylenediamine is disclosed. The improvement rests on the discovery that DSPDA and its salts are extremely sensitive to oxygen so that once the product DSPDA or its salt is formed, oxygen must be excluded from all manipulations.

标 题 :Synthesis of 2-piperazinones and 1,4-diaza-2-keto-cycloheptanes
发明人：LAI JOHN T
权利人:GOODRICH CO B F
摘要:Substituted 2-piperazinones are prepared by reacting a substituted 1,2-diamine with (a) an acyclic or cyclic cyanohydrin acetate, (b) a haloform, and (c) alkali metal hydroxide, in the presence of a suitable organic solvent, at ambient pressure and temperature preferably lower than about 20° C. In an analogous manner, substituted 1,4-diaza-2-keto-cycloheptanes are prepared by reacting substituted 1,3-propane-diamines. In this synthesis, referred to as 'the cyanohydrin acetate synthesis,' the reaction is accelerated with a phase transfer catalyst selected from the group consisting of a polyether, an onium salt, and a tertiary amine. This synthesis yields predominantly a 2-keto-diazacycloalkane with substituents desirably substituted on carbon atoms on either side of the N 4 atom of the diaza ring.

摘要:The disclosure deals with novel synthesis involving (a) hydrogenation of a cis-3,3-dialkyl-3,4-dihydroquinoxaline-2-one in the presence of a suitable hydrogenation catalyst, at elevated temperature and pressure, to yield a cis-3,3-dialkyl decahydroquinoxaline-2-one; (b) reaction of trans-1,2-diaminocyclohexane with acetone cyanohydrin in the presence of water to yield trans-3,3-dimethyl-decahydroquinoxaline-2-one; and (c) a reaction of 1,2-diamine with a saturated acyclic or cyclic monoketone or aldehyde and a holoform, in the presence of (i) a phase transfer catalyst (ii) an organic solvent, and (iii) solid or aqueous alkali to yield 2-keto-1,4-diazacycloalkanes. Such compounds exhibit exceptional UV light stabilizing property.
