摘要：
Interaction of L-OEt(PPh3)(2)RuCl (L-OEt = (eta(5)- C5H5) Co[P(OEt)(2)=O)(3)] with Me3SiC=CH and 2-phenyl-3-butyn-2-ol in the presence of NH4PF6 in MeOH/THF afforded the structurally characterized methoxycarbene [L-OEt(PPh3)(2)Ru=C(OMe)Me]PF6 (1) and the allenylidene complex [L-OEt(PPh3)(2)Ru=C=C=CPhMe]PF6 (2), respectively. The Ru-C distances in 1 and 2 are 1.876(6) and 1.86(2) Angstrom, respectively. The cyclic voltammograms of 1 and 2 exhibit reversible Ru(III/II) couples at 0.58 and 0.64 V vs Cp2Fe+/0 respectively.
