There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

I and i

A review on the latest progress of C-S cross-coupling in diaryl sulfide synthesis: Update from 2012 to 2021

The conversion of enantiomerically enriched (ee >99%) 2α-hydroxypinan-3-one and its oxime (obtained in previously described procedures∗ from α-pinene of 65% ee) into a range of derivatives with potential application in asymmetric synthesis was attempted C2-Symmetrical compounds, ligands for potential catalysts, were synthesized from 2α-hydroxypinan-3-one and either aliphatic or aromatic diamines Reduction or etherification/reduction of selected diiminodiols afforded respective diaminodiols and diaminoethers, which were further transformed into azolium salts Reactions of dipinanediaminoethers with dichlorophenylphosphine and subsequent in situ oxidation of the products afford the respective stable phosphinediamide oxides Four selected compounds were crystallographically studied

Enantiomerically pure α-pinene derivatives from material of 65% enantiomeric purity. Part 2: C2-symmetric N,N'-3-(2α-hydroxy)pinane diimines and diamines

This article discusses the gaps and opportunities within the realm of olefin metathesis technology using ruthenium-based catalysts. Addressing the needs for industrial applications, a straightforward method for the Ring-Opening Metathesis Polymerisation (ROMP) of dicyclopentadiene (DCPD) in a Reaction Injection Moulding (RIM) process is described. Our approach was constituted of the synthesis of a latent Ru catalyst which could be chemically activated on demand. Results provide prove of a high degree of catalyst latency while high catalytic activity is obtained upon addition of Bronsted or Lewis acids. High turn over numbers (TON's) were obtained for the ROMP of cyclo-1,5-octadiene (COD) and dicyclopentadiene (DCPD), respectively 630.000 and 60.000.
