Abstract

The hepta-coordinated isomeric M(NO)Cl3(PN(H)P) complexes {M = Mo, ; W, , PN(H)P = (iPr2PCH2CH2)2NH, (HN atom of PN(H)P syn and anti to the NO ligand)} and the paramagnetic species M(NO)Cl2(PN(H)P) (M = Mo, ; W, ) could be prepared via a new synthetic pathway. The pseudo trigonal bipyramidal amides M(NO)(CO)(PNP) {M = Mo, ; W, ; [PNP](-) = [(iPr2PCH2CH2)2N](-)} were reacted with CO2 at room temperature with CO2 approaching the M[double bond, length as m-dash]N double bond in the equatorial (CO,NO,N) plane trans to the NO ligand and forming the pseudo-octahedral cyclic carbamates M(NO)(CO)(PNP)(OCO) (M = Mo, ; W = ). DFT calculations revealed that the approach to form the isomer is kinetically determined. The amine hydrides M(NO)H(CO)(PN(H)P) {M = Mo, ; W, }, obtained by H2 addition to , insert CO2 (2 bar) at room temperature into the M-H bond generating isomeric mixtures of the η(1)-formato complexes M(NO)(CO)(PN(H)P)(η(1)-OCHO), (M = Mo, ; M = W, ). Closing the stoichiometric cycles for sodium formate formation the isomeric mixtures were reacted with 1 equiv. of Na[N(SiMe3)2] regenerating . Attempts to turn the stoichiometric formate production into catalytic CO2 hydrogenation using in the presence of various types of sterical...Continue Reading

Alpha-Synuclein Aggregation (MDS)

Alpha-synucleins are small proteins that are believed to restrict the mobility of synpatic vesicles and inhibit neurotransmitter release. Aggregation of these proteins have been linked to several types of neurodegenerative diseases including dementia with Lewy bodies and Parkinson's disease. Here is the latest research on α-synuclein aggregation.
