HCl in solution accepts electron density from Au NPs and partially reduces at room temperature, as occurs with other simple diatomic molecules, such as O2 and H2. The activation can be run catalytically in the presence of alkynes to give exclusively E-vinyl chlorides, after the regio- and stereoselective transfer of HCl. Based also on this method, vinyl chloride monomer (VCM) can be produced in a milder and greener way than current industrial processes.

Mercury(II) thiocyanate Hg(SCN)2 catalyses thiocyanic acid HSCN addition to unactivated acetylenic compounds R1-CC-R2.Bonding of the SCN moiety to carbon occurs through sulphur or nitrogen depending upon the influence of R1 and R2; vinyl thiocyanates NCS-C(R1)=CH2 are obtained specifically from terminal acetylenic compounds but some symmetrically disubstituted alkynes may afford vinyl isothiocyanates SCN-C(R1)=CH-R2 ( R1=R2=Et, n-Bu ).A simple preparation of tetraphenylphosphonium hydrogen dithiocyanate Ph4P(1+)*(1-) is reported.
