• The Chemistry of Acylals. 3. Cyanohydrin Esters from Acylals with Cyanide Reagents
  作者：Marcel Sandberg、Leiv K. Sydnes

  DOI：10.1021/ol005535b

  日期：2000.3.1

  [reaction: see text] When treated with KCN in DMSO at room temperature, acylals from aliphatic aldehydes gave the corresponding cyanohydrin esters in good to excellent yields. Acylals from aromatic aldehydes were less reactive and gave several byproducts in addition to fair yields of cyanohydrin under the same conditions. Trimethylsilyl cyanide mixed with titanium(IV) chloride afforded cyanohydrin

  [反应：见正文]在室温下，在DMSO中用KCN处理时，脂族醛的酰基化合物以良好或优异的收率得到相应的氰醇酯。在相同条件下，除了氰醇的合理收率外，芳族醛类的缩醛反应性较低，并产生了几种副产物。氰化三甲基甲硅烷基氰化物与氯化钛（IV）混合可从脂肪族和芳香族醛中获得高至优异收率的氰醇酯。

  Fungal and bacterial growth are inhibited by the use of di-carboxylic acid esters and compositions thereof. In a preferred embodiment, crops and animal feedstuffs are preserved during storage against fungal attack by applying a fungicidal amount of a mono-, di- or trioxymethylene, or lower alkylidene bis-alkanoate, or a mixture thereof. In another preferred embodiment, apple scab is controlled by applying to apple trees a fungicidal amount of a mono-, di- or trioxymethylene bis-alkanoate.

  使用二羧酸酯及其组合物可以抑制真菌和细菌的生长。在一种首选实施方式中，通过施加单-, 二- 或三氧甲基或较低烷基亚甲基双酯或其混合物的杀真菌量，可以在贮存期间保护作物和动物饲料免受真菌攻击。在另一种首选实施方式中，通过施加单-, 二- 或三氧甲基双酯或其混合物的杀真菌量，可以控制苹果树黑星病。

  Fungal growth in animal feedstuffs is inhibited by the use of di-carboxylic acid esters and compositions thereof. In addition to inhibiting the growth of fungi, the di-carboxylic acid esters increase the nutritional value of the animal feedstuff treated, and promote greater weight gain and feed efficiency response in animals fed the treated feedstuff compositions.

• Preparation of alkylidene diesters

  Alkylidene diesters such as ethylidene diacetate are selectively produced in high yields by reacting an ether and/or an ester under substantially anhydrous conditions with carbon monoxide and hydrogen in contact with a catalyst system comprising a rhodium compound, a halogen component, a palladium cocatalyst and a promoter component which is an agent for liberation of carboxylic acid anions. The process is carried out in the liquid phase in a solvent comprising a carboxylic acid at a temperature in the range of 150 to 190°C. and at a carbon monoxide partial pressure in the range from about 1.0 to 1100 kg/ cm2 and a carbon monoxide/hydrogen mole ratio of 6:1 to 1:2 for the ester reaction and 10:1 to 1:2 for the ether reaction. When ethylidene diacetate is the product, it can then be decomposed to produce vinyl acetate and acetic acid by well-known techniques. Since one mole of acetic acid is also produced in the synthesis of the diacetate, the invention makes possible an overall process for the production of vinyl acetate which produces acetic acid rather than consumes it.

  在基本无水的条件下，使醚和/或酯与一氧化碳和氢气反应，并与由铑化合物、卤素组分、钯助催化剂和促进羧酸阴离子释放的促进剂组分组成的催化剂体系接触，可选择性地生产出高产率的亚烷基二酯，如二乙酸亚乙酯。该工艺在液相中，在含有羧酸的溶剂中进行，温度范围为 150 至 190°C，一氧化碳分压范围为约 1.0 至 1100 公斤/平方厘米，酯反应的一氧化碳/氢摩尔比为 6:1 至 1:2，醚反应的一氧化碳/氢摩尔比为 10:1 至 1:2。当产物为二乙酸亚乙酯时，可以通过众所周知的技术将其分解，生成乙酸乙烯酯和乙酸。由于在合成二乙酸乙酯的过程中也会产生一摩尔的乙酸，因此本发明使生产乙酸乙烯酯的整体工艺成为可能，这种工艺生产乙酸而不是消耗乙酸。
