Confirmation of circumstellar phosphine [PDF]
The Astrophysical Journal, 2014 Phosphine (PH3) was tentatively identified a few years ago in the carbon star envelopes IRC+10216 and CRL2688 from observations of an emission line at 266.9 GHz attributable to the J=1-0 rotational transition. We report the detection of the J=2-1 rotational transition of PH3 in IRC+10216 using the HIFI instrument on board Herschel, which definitively ...

Ylide‐Functionalized Phosphines: Strong Donor Ligands for Homogeneous Catalysis
Angewandte Chemie - International Edition, 2018 Phosphines are important ligands in homogenous catalysis and have been crucial for many advances, such as in cross‐coupling, hydrofunctionalization, or hydrogenation reactions. Herein we report the synthesis and application of a novel class of phosphines

Catalytic ammonia formation from dinitrogen, water, and visible light energy [PDF]
Nature CommunicationsThe development of the production method for green ammonia, which is produced only from ubiquitous and clean small molecules (i.e., dinitrogen and water) using renewable energy, has been desired for a next-generation carbon-free energy carrier to build a

Mild Reduction of Phosphine Oxides with Phosphites To Access Phosphines.
Angewandte Chemie International Edition, 2017 A new method for the iodine-catalyzed reduction of phosphine oxides with phosphites at room temperature is reported. The mild reaction conditions, scalability, and simple purification requirements render it a method of choice for the large-scale ...

Chiral phosphines in nucleophilic organocatalysis
Beilstein Journal of Organic Chemistry, 2014 This review discusses the tertiary phosphines possessing various chiral skeletons that have been used in asymmetric nucleophilic organocatalytic reactions, including annulations of allenes, alkynes, and Morita–Baylis–Hillman (MBH) acetates, carbonates ...
