Developing synthetic approaches with non-innocent metalloligands: easy access to Ir(I)/Pd(0) and Ir(I)/Pd(0)/Ir(I) cores.
The development of new, efficient and selective synthetic methods is one of the major goals for future research in chemistry. An important and long-standing challenge in this field is to couple catalytic reactions with redox processes, which is expected to lead to interesting new reactions enabling (radical-type) transformations for substrates that are more difficult or impossible to activate o...
متن کاملSmith GC, Shah I, White IR, Pell JP, Dobbie R
Women with a previous stillbirth are known to be at increased risk of stillbirth in subsequent pregnancies. However, few studies have addressed the association between other complications of pregnancy and the future risk of stillbirth. Using linkage of national pregnancy and perinatal death registries, the authors performed a retrospective cohort study of 133,163 women having a second birth in ...
متن کاملAn optically pure P-alkene-ligated Ir(I) complex.
The asymmetric unit of (P)-chloridobis[(S)-(+)-5-(3,5-dioxa-4-phosphacyclohepta[2,1-a:3,4-a']dinaphthalen-4-yl)dibenz[b,f]azepine]iridium(I)-benzene-pentane (1/1/1), [IrCl(C(34)H(22)NO(2)P)(2)]·C(6)H(6)·C(5)H(12), contains two formula units. The two symmetry-independent molecules of the Ir complex have similar conformations and approximate C(2) symmetry, with small deviations arising from sligh...
متن کاملOh - Ir Stars . I . Physical Properties of Circumstellar Envelopes
A theoretical model of the circumstellar envelope which surrounds a OH-IR star is developed. The circumstellar gas is ejected by radiation pressure which acts on dust grains that condense in the atmosphere of the central star. The dust grains transfer momentum to the gas by collisions with the gas molecules. These collisions are the dominant source of heat input to the circumstellar gas. The ma...
متن کاملRh(I) and Ir(I) catalysed intermolecular hydroamination with substituted hydrazines.
The catalysed intermolecular hydroamination of a series of terminal alkynes with substituted hydrazines was achieved using Rh(I) and Ir(I) complexes.
