Thiocyanatomercuration des acetyleniques. Synthese de derives β-(iso)thiocyanatoalcenyl mercuriques, d'α-halo β-thiocyanato alcenes et de thiocyanato-1 alcynes-1
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 halogens or thio compounds affords α-halo-β-thiocyanatoalkenes. Most of the reported reactions are regio- and stereo-specific, in particular both RC(SCN)CHBr
