摘要：
The cyclic oxacarbene complexes [Ru{CCH2(CH2)(n)CH2O)(dppe)(eta-C5H5)[PF6] (dppe = Ph(2)PCH(2)CH(2)PPh(2); n = 1, 1 or 2, 2) have been synthesised by reaction of hydroxyalk-1-ynes, HC=C(CH2)(n)CH2OH with [RuCl(dppe)(eta-C5H5)]/NH4[PF6] in refluxing methanol. The X-ray crystal structures of 1 and 2 reveal essentially vertically orientated carbene ligands with the oxygen directed 'down' away from the cyclopentadienyl ring. Both carbene rings exhibit folded conformations; the five-membered ring of 1 adopts an envelope configuration whilst the six-membered ring of 2 has a boat conformation.
