N2 - Reaction of [RuClH(CO)(PPh3)2(BSD)] (BSD = 2,1,3-benzoselenadiazole) with the propargylic alcohols HCC-CR2OH (CR2 = CMe2 or cyclo-C6H1O) leads to the σ-vinyl derivatives [RuCl(CHCH-CR2OH)(CO)(PPh3)2(BSD)] whereas the same alcohols when treated with [RuClH(CO)(PPh3)3] followed by BSD yield (via [RuCl(CHCHCR2OH)(CO)(PPh3)2,3]), the dehydrated σ-dienyl compounds [RuClCHCHC(CH2)Me(CO)(PPh3)2(BS], [RuClCH CHC6H9(CO)(PPh3)2(BSD)]. The last complex is also the product of the reaction of [RuClH(CO)(PPh3)2(BSD)] with 1-ethynyl cyclohexene. Dehydration of the vinylic alcohol complexes is also induced by trifluoroacetic anhydride.
