Mechanistic Study of the N-Formylation of Amines with Carbon Dioxide and Hydrosilanes

Paul Joseph Dyson, Gabor Laurenczy, Martin Hulla

N-formylation of amines with CO2 and hydrosilane reducing agents proceeds via fast and complex chemical equilibria, which hinder easy analysis of the reaction pathways. In situ reaction monitoring and kinetic studies reveal that three proposed pathways, vi ...

Antiproliferative activity of ruthenium and osmium clusters with phosphine ligands

Paul Joseph Dyson, Alexey Nazarov

New ruthenium and osmium carbonyl clusters with 1,3,5-triaza-7-phosphatricyclo-[3.3.1.13.7]decane and 3,7-diacetyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane ligands were synthesized using Me3NO as an initiator. The data on antiproliferative activity of ne ...

Quantitative aqueous phase formic acid dehydrogenation using iron(II) based catalysts

Gabor Laurenczy, Andrew Francis Dalebrook, Mickael Montandon-Clerc

We present here the results of our investigation on aqueous phase formic acid (FA) dehydrogenation using non-noble metal based pre-catalysts. This required the synthesis of m-trisulfonated-tris[2-(diphe nylphosphino)ethyl]phosphine sodium salt (PP3TS) as a ...

Design strategy for controlled natural aging in Al-Mg-Si alloys

William Curtin

This study presents a design strategy for Al-Mg-Si alloys to control natural aging. Recently, trace addition of Sn was shown to suppress natural aging for up to two weeks, which was explained by the strong trapping of vacancies to Sn atoms. Here we explore ...
