  醛/醇与醇的无金属无受体脱氢交叉偶联

  摘要：

  尽管在过去十年中，过渡金属催化的脱氢交叉偶联反应在获得碳-碳键和碳-杂原子键方面取得了巨大成功，但无金属无受体的脱氢交叉偶联反应仍然稀缺且非常可取。在这里，我们报告了一种用于碳-杂原子和碳-碳键形成的稳健的无金属无受体脱氢交叉偶联。通过有机光催化剂4CzIPN和硫醇在蓝光照射下的协同催化，醛与醇或两种不同醇的交叉偶联反应顺利进行，具有广泛的底物范围和良好的官能团相容性，以令人满意的收率提供相应的酯类以及氢气的释放。这种无金属的氧化还原中性过程也实现了导致芴酮衍生物的脱氢分子内酰化。机理研究表明，在光催化条件下，酰基会产生并随后氧化成其阳离子。

  A process is described for producing acetals comprising reacting an aldehyde or a ketone with an alcohol in the presence of a titanium compound having an acetylacetone as a ligand, or in the presence of a compound selected from the group consisting of stannous chloride dihydrate, cerium chloride hexahydrate and bismuth chloride. The process can be used in the synthesis of unstable acetals or when water exists in the reaction mixture, and therefore the process can be used for a wide variety of applications.

  描述了一种生产缩醛的过程，包括在存在乙酰丙酮作为配体的钛化合物或在存在从氯化亚锡二水合物、六水合氯化铈和氯化铋组成的化合物中，将醛或酮与醇反应。该过程可用于合成不稳定的缩醛，或者当反应混合物中存在水时，因此该过程可用于各种各样的应用。

  An air freshening composition including porous carrier particles having a perfume composition entrapped therein, and a second component selected from an inert filer, hygroscopic agent, binder, coating material, moisture providing agent, and mixtures thereof. The composition may further comprise various optional components such as free perfumes, colorants, disintegrants, water swelling agents, porosity modifiers and mixtures thereof. A method for processing the compositions into a solid article includes the steps of entrapping a perfume in the porous carrier particles, heating and incorporating a carrier or binder material. The compositions may be further processed by optionally incorporating a powder inert filler and forming articles from the mixture. The articles may be formed from the compositions through prilling, extrusion, or compaction amongst other techniques. The air freshening articles and compositions will provide a sustained and controlled release of the perfume compositions over a long period of time without the use of a heat to activate the release. Articles of manufacture including the air freshening articles and various packaging are also disclosed.
