摘要:
[Ru(CO)(2)(PPh3)(3)] reacts with [Me3SiC CPPh3]OTf in the presence of moist [(Bu4N)-Bu-n]F to provide the C-H activation product [RuH(C CPPh3)(CO)(2)(PPh3)(2)]OTf, spectroscopic and structural data for which are used to assess the previously proposed analogy between phosphoniacetylide and phosphaallenylidene (cf. isonitriles) bonding descriptions in an organometallic context.
