Investigations on the Coupling of Ethylene and Alkynes in Tp Me2 Ir Compounds: Water as an Effective Trapping Agent

Álvarez González, Eleuterio Paneque Sosa, Margarita Martín Posadas, Cristina Isabel

The reaction of the bis(ethylene) complex [TpMe2Ir(C2H4)2] (1) (TpMe: hydrotris(3,5-dimethylpyrazolyl)borate) with two equivalents of dimethyl acetylenedicarboxylate (DMAD) in CH2Cl2 at 25 °C gives the hydride–alkenyl species [TpMe2IrH{C(R)=C(R)C(R)=C(R)CH=CH2}] (2, R: CO2Me) in high yield. A careful study of this system has established the...

Reactivity of TpMe2-containing hydride-iridafurans with alkenes, alkynes, and H2

Vivancos Ureña, Ángela Martín Posadas, Cristina Isabel Hernández, Yohar A.

The TpMe2-containing hydride-iridafurans 2a,b (TpMe2 = hydrotris(3,5-dimethylpyrazolyl)borate) cleanly reacted with ethylene to give the bicyclic derivatives 6a,b. Formation of the latter complexes is a reversible process, and it is proposed to occur by an electrocyclic ring closure that takes place between C2H4 and the 16e unsaturated...
