Carbonyl groups from bridging phosphaketenyl ligands in Mn2(CO)8(μ-PCO)2 are predicted to migrate from phosphorus to manganese upon decarbonylation, giving the diphosphido Mn2(CO)n+2(μ-P2) derivatives.

New Type

The aim of this work is to develop a new type of polymer matrix which can be used to study the reactive intermediates produced from UV photolysis of metal carbonyl complexes measured with FTIR as well as UV-vis spectroscopy. The photochemistry of Cr(CO)6 impregnated in Teflon-AF polymer with the presence of N2, CH4 and even weak ligand i.e.Xe and He were conducted at extremely low temperature.  Photolysis of Cr(CO)6 under N2 environment produces up to four carbonyl groups being replaced with the N2. Meanwhile, the photochemistry of Cr(CO)6 under Xe and CH4 produce the reactive complexes of Cr(CO)5(Xe) and Cr(CO)5(CH4)respectively. Teflon-AF was found to be the suitable matrix material as the –C–F– bond binds very weakly to the metal center.

Abstract Selected recent advances in immunoassay are reviewed. Development has continued on new labels (beta-lactamase, pyrophosphatase, luciferases, photoproteins, pyridopyridazines, europium cryptates, metal carbonyl complexes, porphines, phosphors) and label-detection methods (e.g., chemiluminescence assays, thermometric assays, NADP(+)- and FADP-based coupled assays). Various methods have been explored to increase assay sensitivity, including label amplification via catalyzed reporter deposition (peroxidase label) and immuno-polymerase chain reaction (DNA label). The focus of new immunoassay strategies has been on improved reliability (bispecific antibodies), assay simplification (piezoelectric and surface plasmon resonance immunosensors, phase-modulation fluorescence spectroscopy, polymerized bilayer assemblies), and simultaneous multianalyte testing (e.g., quadruple labeling with lanthanides, one-step test devices for drugs of abuse).

The stereochemistry of epoxide carbonylation using bimetallic [Lewis acid]+[Co(CO)4]- complexes is reported. The achiral complex [(salph)Al(THF)2][Co(CO)4] stereospecifically carbonylates cis- and trans-2-butene oxide to the trans- and cis-β-lactones, respectively. Preliminary experiments regarding the carbonylative kinetic resolution of racemic trans-2-butene oxide using the enantiomerically pure complex [(R,R-salcy)Al(THF)2][Co(CO)4] are also reported.
