Otto Billeter or How the Oldest [3,3]-Sigmatropic Rearrangement went to Neuchâtel, Part 2 Otto Billeter oder wie die älteste [3,3]-sigmatrope Umlagerung nach Neuenburg kam: Teil 2

CHIMIA, 2000
The historical survey of the uncatalyzed, thermal rearrangement of thiocyanates into isothiocyanates is continued, starting with a review of Otto Billeter's scientific and social career in Neuchâtel. A specific look is taken at 1925 where Ludwig

General and Practical Formation of Thiocyanates from Thiols [PDF]

, 2014
A new method for the cyanation of thiols and disulfides using cyanobenziodoxol(on)e hypervalent iodine reagents is described. Both aliphatic and aromatic thiocyanates can be accessed in good yields in a few minutes at room temperature starting from a ...

High‐Density‐Cluster Ru Catalyst Substitute for Pt/C Benchmark Improves Membrane Water Electrolysis

Advanced Science, EarlyView.
Yuan et al. report a high‐density, monodispersed Ru cluster catalyst featuring interfacial covalent bonds that modulate the electronic structure and optimize intermediate adsorption–desorption, thereby conferring pH‐universal HER activity with ampere‐level current densities and enabling the development of Pt‐free membrane electrodes.

An Efficient and Eco-Friendly Procedure for Electrophilic Thiocyanation of Anilines and 1-(Substituted benzylidene)-2-phenyl Hydrazines

Chemistry
Thiocyanates form an important class of organic compounds commonly found in natural products that exhibit excellent antimicrobial activity. The electrophilic thiocyanation is one of the most effective methods of introducing a -SCN functional group to the

[3,3]-Sigmatropic Rearrangements of Fluorinated Allyl (Thio)cyanates – A Tool for the Synthesis of Fluorinated (Thio)ureas

CHIMIA, 2014
The first (thio)cyanate to iso(thio)cyanate rearrangements based on 2-fluoroallylic alcohols are presented. Long-chain 2-fluoroallylic alcohols were converted to corresponding N-unsubstituted carbamates by treatment with trichloroacetyl ...

Reductive dimerization of organic thiocyanates to disulfides mediated by tetrathiomolybdate

, 1995
An interesting reductive dimerization of organic thiocyanates assisted by benzyltriethylammonium tetrathiomolybdate, [(PhCH(2)NEt(3))(2)MoS4], 1, leads to the formation of the corresponding disulfides in high ...
