Phosphine Organocatalysis [PDF]
Chemical Reviews, 2018 The hallmark of nucleophilic phosphine catalysis is the initial nucleophilic addition of a phosphine to an electrophilic starting material, producing a reactive zwitterionic intermediate, generally under mild conditions. In this Review, we classify nucleophilic phosphine catalysis reactions in terms of their electrophilic components. In the majority of

Pesticidal Toxicity of Phosphine and Its Interaction with Other Pest Control Treatments
Current Issues in Molecular Biology, 2023 Phosphine is the most widely used fumigant for stored grains due to a lack of better alternatives, all of which have serious shortcomings that restrict their use.

Coordination chemistry with phosphine and phosphine oxide-substituted hydroxyferrocenes
Dalton Transactions, 2010 New unsymmetrical hydroxyferrocenes were synthesised from dibromoferrocene. The oxygen heteroatom was introduced via lithiation and quenching with bis-trimethylsilylperoxide followed by hydrolysis to unmask the hydroxyl functionality. The coordination chemistry of 1'-(diphenylphosphino)-1-hydroxyferrocene 2 was explored with palladium and rhodium ...

Phosphine gas in the cloud decks of Venus [PDF]
Nature Astronomy, 2020 Measurements of trace gases in planetary atmospheres help us explore chemical conditions different to those on Earth. Our nearest neighbour, Venus, has cloud decks that are temperate but hyperacidic. Here we report the apparent presence of phosphine (PH3)

Responses of phosphate transporter gene and alkaline phosphatase in Thalassiosira pseudonana to phosphine. [PDF]
PLoS ONE, 2013 Phosphine, which is released continuously from sediment, can affect the eco-physiological strategies and molecular responses of phytoplankton. To examine the effects of phosphine on phosphorus uptake and utilization in Thalassiosira pseudonana, we ...
