La presente invención se refiere a diversos complejos catiónicos de los metales cobalto, rodio e iridio conteniendo ligandos de tipo ciclopentadienilo (Cp') y una fosfina metalada y a su uso como catalizadores en un procedimiento para la preparación de si
A catalytic synthesis of deuterated silanes SiEt3D, SiMe2PhD and SiPh2D2 is reported that allows their facile generation in a 3–4 g scale, utilizing D2 (0.5 bar) as the hydrogen isotope source and low catalyst loadings (0.01 mol%). The catalyst precursor is the rhodium (III) complex 1, which contains a (η5‐C5Me5)Rh cation stabilized by...
Complexes TptolRh(C2H4)2 (1a) and TptolRh(CH2C(Me)C(Me)CH2) (1b) have been prepared by reaction of KTptol with the appropriate [RhCl(olefin)2]2 dimer (Tptol means hydrotris(3-p-tolylpyrazol-1-yl)borate). The two complexes show a dynamic behaviour that involves exchange between κ2 and κ3 coordination modes of the Tptol ligand. The iridium...
In this contribution we study experimentally and computationally some electrophilic cationic (η5-C5Me4R)RhIII complexes containing a cyclometalated bis(aryl) phosphine, PR′Ar2. The phosphine Ar groups feature methyl substituents at the 2- and 6-positions of the aromatic rings, allowing the formation of the complexes [(η5-C5Me4R)Rh(C^P)]+ (3+),...
