A new small family of Ru, Rh, and Ir piano-stool complexes partially containing the bulky acacdiMes, p-Cymene and Cp* ligands was synthetized and characterized. Their catalytic activity in transfer hydrogenation reaction was tested. The turn over fre

In this contribution we study experimentally and computationally some electrophilic cationic (η-CMeR)Rh complexes containing a cyclometalated bis(aryl) phosphine, PR′Ar. The phosphine Ar groups feature methyl substituents at the 2- and 6-positions

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 pre

The properties of a novel Gd(3+)-based MRI zinc sensor are reported. Unlike previously reported Gd(3+)-based MRI contrast agents, this agent (GdL) differs in that the agent alone binds only weakly with human serum albumin (HSA), while the 1:2 GdL:Zn(
