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

The reaction of [RuClH(CO)(PPh3)3] with bis(alkynyl)mercurials [Hg(C = CR)2] (R = Ph, C6H4Me-4, nC4H9, CMe2OH) leads to the formation of the coordinatively unsaturated but-3-en-l-yn-3-yl complexes [RuC(C = CR) = CHR}Cl(CO)(PPh3)2].
