The quantitative conversion of cyclohexene to cyclohexane was obtained in 5h at 25 °C using 0.1 mol % of (1A) in methanol solution at 15 atm H 2 . The substituted bipy derivatives (2) and (3) were also effective pre-catalysts, but pseudohalides were not under these conditions....

摘要: Chlorination of α-seleno-aldehydes bearing an α-hydrogen gives selenium dichlorides which decompose into α-chloro α-seleno-aldehydes and α-chloroenal. Bromination, in all cases, and chlorination for the other α-seleno-aldehydes lead to the α-halogenoaldehydes....

The use of free ion charges instead of partial charges in crystals of high covalent character is the main reason of the failures of VBTA. Fig. 5.2 shows the percent error in UVBT, % error = [100(UVBT−UBHF)/UBHF] versus Pauling electronegativity difference Δχ for 37 monohalides ...
The metal-carbon bonds of the four-membered metallacycles [(MeSi)N]MCHSiMeNSiMe(M=U, Th) reacts with carbonyl compounds to give the six-membered metallacycles [(MeSi)N]M-OC(RR')-CHSiMeNSiMe. Acidic hydrogens reacts under mild conditions... A Dormond,AAE Bouadili,C Moise - 《Jour...
Tennessine is the latest addition to the halogen family and is named after the state of Tennessee, US; but it is still not considered a true halogen because it is a synthetic element. When halogens combine with metals, salts are formed. The salts are called halides. Individually, these ...
This rhodium-catalysed auto-tandem reaction operates under mild, environmentally benign conditions using water as the solvent and CO surrogates as the carbonyl source with the concomitant generation of hydrogen gas. The strategy may facilitate the development of new synthetic protocols for the efficient ...
