标题:含季organic和叔磷的新型功能性有机网络
摘要:通过镍(0)催化的山本型交叉偶联反应获得季phospho和叔磷官能化的微孔聚合物.信号的积分比(季phospho与叔磷原子)接近3:2.聚合物网络对水,碱和酸是稳定的,甚至在材料用10 M Hcl处理后,实际上也没有观测到表面积的变化.用horvath-Kawazoe方法计算出的孔径分布表明存在平均宽度约为0.7和1.4 Nm的微孔.它们的表观bet比表面积可被调谐(650至980米2克-1通过改变抗衡(br)-到f-).对于环氧化物和co 2之间的反应,它表现出很高的固有催化活性(收率:98%,1个大气压).还制备了负载在聚合物网络上的pd纳米粒子,该粒子对1-氯苯与苯基硼酸之间的交叉偶联反应表现出较高的催化活性(收率:> 95.8%).

权利人:MASTROIANNI SERGIO; INVISTA NORTH AMERICA SARL
摘要:A process for the hydrocyanation of a hydrocarbon-based compound having at least one site of ethylenic unsaturation into a nitrile compound includes reaction thereof, in a liquid medium, with hydrogen cyanide in the presence of a catalyst containing a metal element selected from among the transition metals and an organophosphorus ligand, wherein the organophosphorus ligand is a mixture of at least one monodentate organophosphite compound and at least one monodentate organophosphine compound; the subject process is especially useful for the synthesis of adiponitrile from butadiene.

标题:Methods for the synthesis of phosphonate esters
发明人：CAMPBELL DAVID A
权利人:AFFYMAX TECH NV
摘要:Phsophonate esters can be synthesized in high yields by condensations of alcohols with methyl phosphonates followed by selective demethylation. The reaction is general, relativly insensitive to steric constraints of hindered phosphonic acids, and can also be carried out on a solid support to synthesize large collections of compounds to screen for pharmacological activity.

摘要:Disclosed is a silyl thioalkene compound, as a class of organosilicon compounds, represented by the general formula n n R(--CSArâ•?CHSiX.sub.3).sub.n, n n in which the subscript n is 1 or 2, R is, when n is 1, a hydrogen atom or unsubstituted or substituted monovalent hydrocarbon group or, when n is 2, a divalent hydrocarbon group, Ar is an unsubstituted or nucleus-substituted aromatic monovalent aromatic hydrocarbon group and X is a halogen atom, a monovalent hydrocarbon group or hydrocarbyloxy group, having usefulness as an intermediate in the synthesis of various precision organic chemicals. The compound, of which X is a halogen atom X 1 , can be prepared, for example, by the reaction of an alkyne compound of the general formula n n R(--C.tbd.CH).sub.n, n n with a silyl sulfide compound of the general formula n n ArS--SiX.sup.1.sub.3, n n in the presence of a platinum complex catalyst. The compound, of which X is a monovalent hydrocarbon group or a hydrocarbyloxy group, can be derived from the above obtained halogen-containing compoud.
