The compound [Ru(CHCHCPh2OH)(κ2-L4)(CO)(PPh3)2] can be dehydrated by reaction with HBF4 to yield the vinylcarbene species [Ru(CHCHCPh2)(κ2-L4)(CO)(PPh3)2]BF4. The complexes [RuR(κ2-L6)(CO)(PPh3)2] (R = H, CHCH2, CHCHC6H4Me-4, C(C⋮CPh)CHPh) were prepared from pyrrole-2-carboxaldehyde (HL6), the oxygen analogue
