Speciation Analysis and Environment
The determination of methylmercury in biological samples by HPLC coupled to ICP-MS detection (p 303-310)

DOI: 10.1002/aoc.1173
The use of high performance liquid chro-matography (HPLC) coupled to inductively coupled plasma mass spectrometry (ICP-MS) for the determination of methylmercury (MeHg+) in fish tissue and hair samples is described. The developed protocol can be used with atmospheric pressure ionization mass spectrometry (API-MS) to provide structural characterization and also with calibration via isotope dilution (IDMS) to provide high accuracy quantitation of MeHg+ in biological samples used in biomonitoring studies. | |

There are three characteristic reactions of organocobalt compounds in organic syntheses. The first involves the reactions of a mutually bridged bond between the two | |
-bonds of acetylene and the cobalt-cobalt bond of hexacarbonyldicobalt, the second one is carbonylations, and the third one is reactions with vitamin B12 type compounds. A new CuAl-hydrotalcite catalyzed homocoupling reaction of terminal alkynes at room temperature (p 345-349)

DOI: 10.1002/aoc.1212
CuAl-LDH has been prepared and applied in the homocoupling reaction of a variety of terminal alkynes at room temperature. The Cu (II) in the host layers of the hydrotalcite exhibits high activity and the catalyst can be easily recovered and reused for eight cycles without depreciation of catalytic activity. | |
A new 3s-3d heterometallic polymer containing N-methyliminodiacetic acid: synthesis, structure and characterization (p 350-354)

A new complex {[Na2(H2O)3(µ-L)2Cu]4} | |
(L = N-methylimino diacetic acid) has been synthesized and structurally characterized. The structure consists of CuL2 moieties linked by sodium chain via the exo oxygen atoms of two ligands, forming a novel three-dimensional structure. IR, UV-vis, ESR spectroscopy and thermal stability were determined. Dppc+PF6--PdCl2-[bmim][PF6]-a copper-free recyclable catalytic system for Sonogashira coupling reaction (p 355-359)

An air-stable, copper-free and highly efficient Dppc+PF6- - PdCl2 - [bmim][PF6] catalytic system has been developed for the Sonogashira coupling reaction of aryl iodides with various aryl- and alkylacetylenes. The catalytic system allows for the facile separation and can be recycled at least eight times with minimal loss of activity. | |
Synthesis, characterization and properties of novel polyamides containing ferrocene unit and flexible spacers (p 360-367)

Published Online: Apr 2 2007 8:50AM
DOI: 10.1002/aoc.1191
A series of ferrocene-based polyamides with flexible spacers was prepared via polycondensation reaction of a new ferrocenyl diamine (FDADO) with different diacid chlorides. The polymers showed heat- and flame-resistancy and improved solubility. | |

Published Online: Apr 2 2007 8:50AM
DOI: 10.1002/aoc.1204
NbF5 acts as a highly effective catalyst for cyanosilylation of variousetones to the corresponding cyanohydrin trimethylsilyl ethers in excellent yield. The reaction proceeds smoothly with 1 mol% catalyst loading at room temperature under solvent-free conditions. | |
Studies on the reaction of organotin phenoxides with ethyl propiolate catalysed by triethylamine and tin(IV) chloride (p 373-376)

DOI: 10.1002/aoc.1216
A new method of synthesis of 3-phenoxyacrylic acid ethyl esters, coumarin and 6-methylcoumarin has been elucidated. This procedure is based on the reaction of different organotin phenoxides, prepared by the azeotropic dehydration of the mixture of phenols and bis(tributyltin) oxide in toluene, with ethyl propiolate catalysed by Et3N or SnCl4. | |
