Vinylidene ruthenium complexes were prepared from trichloronitrosylbis(phosphine)rutheniums and terminal alkynes, subsequent cycloaddition of methyl propiolate to the vinylidene complexes giving rise to unusual ruthenacyclobutene species; in these transformations, an interesting electrostructurally-flexible behaviour of the NO ligand was observed.

The order of discovery can have a profound effect upon the way in which we think about the function of a gene. In E. coli, recA is nearly essential for cell survival in the presence of DNA damage. However, recA was originally identified, as a gene required to obtain recombinant DNA molecules in conjugating bacteria. As a result, it has been frequently assumed that recA promotes the survival of ...

In recent years, the construction of commercial complexes has been increasingly grown across the country. However, only some of them have been successful to accommodate a large number of visitors while others are constantly changing the commercial units’ use. Meanwhile the lack of demand for commercial units in the form of multi-purpose complexes as well as recent general recession in the count...

The reaction of trans-[Fe(R-bpb)(CN)2]- (R-bpb2-=R-substituted-1,2-bis(pyridine-2-carboxamido)benzenate) with trans-Mn(III) Schiff base complexes [Mn(5-X-saltn)]ClO4 (5-X-saltn2-=N,N'-propanolbis(5-X-substituted-salcylideneiminato) dianion) gave rise to cyanide-bridged neutral binuclear [MnFe] compounds [Mn(saltn)(MeOH)][Fe(bpb)(CN)2].3H2O (), [Mn(saltn)(H2O)Fe(bpmb)(CN)2].H2O (), [Mn(saltn)(Me...

today, urbanization (living at apartments) phenomenon as the most common type of residence of cities has been changed so that mainly reflects the chaos in this area. too much attention paid to economic indicators compromised the balance in the housing sector and created a new type of buildings. the occurred changes indicate ignoring cultural characteristics, less attention paid to cultural conc...

We describe the reactivity of hypersilyl-functionalized Zintl cluster salt K[Ge9(Hyp)3] towards nickel reagents Ni(COD)2 and Ni(Cp)2, which gives rise to markedly different complexes.
