Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn¡¯t involve a screen. 32993-05-8, C41H35ClP2Ru.

eta1-Vinylidene formation from internal alkynones by C-C bond migration
The [mu2-N2(CpRu(PPh3)2) 2]2+ (12+) dication is a source of the formal 16-electron [CpRu(PPh3)2]+ fragment, and it reacts with internal alkynes such as 1,3-diphenylpropynone, 4-phenyl-3-butyn-2- one, and 3-cyclopropyl-1-phenylpropynone to yield eta1-vinylidene complexes 2a+-2c+ by C-C bond activation. In the case of 1,3-diphenylpropynone, the eta1-ketone complex [CpRu(PPh 3)2{PhC(eta1-O)C?CPh}]+ (3a+) was isolated as its PF6- salt, and it is apparently an intermediate in the formation of the vinylidene complex. Complexes 2a+-2c+ were characterized as their BArF 4- [ArF = 3,5-bis(trifluoromethyl)phenyl] salts by NMR and IR spectroscopic methods, ESI-MS, and EA. The single crystal X-ray diffraction structure of 2aBArF4 is presented. These reactions represent the first examples where an internal alkyne undergoes C-C bond migration to form an eta1-vinylidene complex. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.
