摘要:通过处理碱性层状双氢氧化物,水滑石(ht,Mg(6)al(2)(oh)( 16)co(3))与rucl(3)n H(2)o和k(2)[pdcl(4)]水溶液分别使用表面浸渍法.通过x射线衍射,能量色散x射线,电子顺磁共振和x射线吸收精细结构光谱分析,证明了ru(iv)单体已接枝到ht的表面.同时,在减少表面分离的pd(II)种类之后,通过透射电子显微镜分析在pd(纳米)/ Ht表面上观测到平均直径为约70A的高度分散的pd纳米团簇.这些水滑石负载的金属催化剂可通过由金属催化的氧化和还原组成的串联反应,以及由ht的碱位促进的羟醛反应,有效地促进各种腈与伯醇或羰基化合物的α-烷基化反应.在这些催化的α-烷基化反应中,均质的碱是不必要的,唯一的副产物是水.另外,这些催化剂体系适用于戊二腈衍生物的一锅法合成.

标 题 :Synthesis of cyanoacrylate esters by oxidation of aromatic selenyl cyanopropionates

摘要:A method of preparing an α-cyanoacrylate ester of a desired alcohol includes the steps of n preparing a compound which is an α-selenoaryl-α-cyanopropionate ester of the desired alcohol, n oxidizing said α-selenoaryl-α-cyanopropionate ester to the corresponding selenoxide, n eliminating arylselenic acid from the selenoxide to produce said α-cyanoacrylate ester, and n separating said α-cyanoacrylate ester from the selenic acid. n At temperatures of about 0° C. or higher, the elimination step occurs concurrently with the oxidizing step using a peroxide or ozone oxidizing agent. The desired cyanoacrylate ester is obtained in good yield and very high purity. The method can be used to prepare difficult to synthesize plural functional cyanoacrylate monomers and mono- cyanoacrylate monomers regardless of alcohol chain length.
