N2  - Reactions between &#969;-hydroxyalk-1-ynes, HC2(CH2)nOH (n = 2 or 3) or HC2CH2CHMeOH, and MX(PR3)2(&#951;-C5H5) (M = Ru, X = Cl, R = Me or Ph; M = Os, X = Br, R = Ph) in the presence of NH4PF6 give cationic cyclic carbene complexes, presumably by rapid intramolecular cyclization of (undetected) intermediate &#969;-hydroxyvinylidene complexes. Further reactions of {Ru[C(CH2)3O]-(PPh3)2(&#951;-C5H5)}+ include (a) base-catalysed H- D exchange of both H atoms of the &#946;-CH2 group; (b) metallation and subsequent dimethylation of the &#946;-CH2 group; (c) reduction by NaAlH2- (OCH2CH2OMe)2 to Ru[CH(CH2)3O](PPh3)2(&#951;-C5H5).
