, p. 294 - 302 (2015)
The one-pot anodic thiocyanation and isothiocyanation of alkenes in both acidic two-phase (water-dichloromethane) and homogeneous one-phase (water-acetonitrile) media has been studied. Optimisation experiments on tetramethylethylene as a model alkene invo

In the presence of (SCN)- mercuric chloride HgCl2 adds to acetylenic compounds R1CCR2 affording in most cases α-chloromercuri-β-thiocyanatoalkenes R1C(SCN)=C(R2)HgCl and if R1 = R2 = Et or n-Bu isothiocyanates R1C(NCS)=C(R2)HgCl.The action of halogenes or thiocyanogen (SCN)2 on organomercuric compounds affords α-halo-β-thiocyanatoalkenes.Most of the reported reactions are regio- and stereo-specific, in particular both RC(SNC)=CHBr and RCBr=CHSCN may be regiospecifically obtained from 1-alkenes RCCH.The synthesis of 1-thiocyanato-1-alkynes is also reported.

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.
