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. 92361-49-4, C46H45ClP2Ru.

Ethinylkomplexe des rutheniums mit terminalen hauptgruppenelement-substituenten: Systematischer aufbau metallgebundener phosphoniumacetylid-liganden R?R2P(+)-C?C|(-)
Treatment of Cp*RuL2Cl (Cp* = C5Me5; L = PPh3, PMe3) with Me3SiC?CH in the presence of NH4[PF6] in CH2Cl2 yielded the expected vinylidene compounds [Cp*RuL2=C=CH2][PF6] with L = PPh3 (1) and PMe3 (1a), which were deprotonated by KOBut in THF to give the corresponding ethynyl complexes Cp*Ru(PPh3)2C?CH (2) and Cp*Ru(PMe3)2C?CH (2a). Metalation of 2 using n-BuLi or t-BuLi in THF-hexane, followed by reaction of the lithio intermediate Cp*Ru(PPh3)2C?CLi with ClER3 (E = Si, Ge, Sn) or C1PR2, resulted in the formation of substituted derivatives, Cp*Ru(PPh3)2C?CER3 [ER3 = SiMe3 (3), GeMe3 (4), SnBun3 (5)] and Cp*Ru(PPh3)2C?CPR2 [PR2 = PPh2 (6), PBut2 (7)] respectively. Quaternization of 6 and 7 by alkyl iodides in toluene smoothly produced phosphonioethynyl complexes, [Cp*Ru(PPh3)2C?CPR2R?]I [PR2R? = PPh2Me (8), PBut2Me (9), PPh2Prn (10), PBut2Prn (11)], the cations of which may be regarded as donor/acceptor-stabilized derivatives of dicarbon, C2.
