标题:酒精基米利斯-阿尔布佐夫反应:一种有效且环境友好的c-p(o)键形成方法
摘要:著名的米利斯-阿尔布佐夫(michaelis-Arbuzov)反应每年在实验室和工业中得到广泛使用,以生产数吨广泛使用的有机磷酰基化合物.但是,该方法和最近开发的改进的michaelis-Arbuzov反应仍然存在一些局限性.现在,我们报告迈克尔斯-阿布佐夫(michaelis-Arbuzov)反应的一种新的酒精转化形式,它可以提供一种有效且对环境有益的方法来解决已知的迈克尔斯-阿布佐夫(michaelis-Arbuzov)反应的问题.即,使用正丁基4,各种各样的醇可以容易地与亚磷酸酯,亚膦酸酯和次膦酸酯反应,反应生成所有三种磷酰基化合物(膦酸酯,次膦酸酯和氧化膦).ni催化的高效c-p(o)键形成反应.这种通用方法也可以轻松按比例放大,并在一锅中用于进一步的合成转化.

标 题:1,1-diborylalkyl-1-metal compounds, preparation method thereof, and their applications toward synthesis of 1,1-diboronate ester compounds
发明人：CHO SEUNG HWAN; LEE YEOSAN
权利人:POSTECH ACAD IND FOUND
摘要:The present invention relates to a 1,1-diborylalkyl-1-metal compound including one metal group together with two identical boron groups at the sp3 carbon center, and its use. Specifically, the present invention relates to development of novel organic reactions, synthesis of functional molecules, and synthesis of new drugs by applying the novel 1,1-diboryl-1-metal substituted alkyl compounds to various molecular libraries which could not be synthesized by conventional methodologies.

标 题 :Synthesis of cyclic ethers
发明人：SCHEBEN JOHN A
权利人:NAT DISTILLERS CHEM CORP
摘要:A process is disclosed for preparing a cyclic ether which comprises cyclodehydrating a polyhydroxy compound of the general formula n n HOR.sup.1 HC--R.sup.2 --CHR.sup.3 OH n n in which R 1 and R 3 , each of which is the same or different, is hydrogen or a lower aliphatic, cycloaliphatic or aryl group and R 2 is a divalent aliphatic group of 1 to 10 carbon atoms containing 0, 1 or 2 etheric oxygen atoms or 0, 1 or 2 secondary or tertiary amine nitrogen atoms and 0, 1 or more lower aliphatic, cycloaliphatic and/or aryl groups containing 0 or 1 hydroxyl groups at elevated temperatures in the presence of a catalytically effective amount of a Group VIII metal catalyst or a Group VIII metal-containing material to provide a cyclic ether of the general formula ##STR1## in which R 1 , R 2 and R 3 are as defined above. The process is especially useful for preparing the commercially important cyclic ethers tetrahydrofuran and 1,4-dioxane which are derived from 1,4-butanediol and ethylene glycol and/or diethylene glycol, respectively.
