Chemistry is an experimental science, Formula: C10H16BrN, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 5350-41-4, Name is N,N,N-Trimethyl-1-phenylmethanaminium bromide
New supraicosahedral metallacarboranes. The synthesis and molecular structures of 4-dppe-4,1,6-closo-NiC2B10H12 and [4-(eta-C3H5)-4-(CO)2-4,1,6-closo-MoC 2B10H12]-
The new 13-vertex nickelacarborane 4-dppe-4,1,6-closo-NiC2B10H12 and molybdacarborane [4-(eta-C3H5)-4-(CO)2-4,1,6-closo-MoC 2B10H12]- have been prepared. The structure of the CH2Cl2 solvate of the nickel species has been studied as two crystalline modifications. The molybdacarborane was also studied crystallographically as its [PhCH2NMe3]+ salt. The differing trans influences of C and B atoms in the metalla-bonded C2B4 carborane ligand face are used to rationalise the difference in Ni-P distances in the nickelacarborane and the orientation of the {Mo(C3H5)(CO)2} fragment in the molybdacarborane. Both metallacarboranes display fluxionality in solution at room temperature which can be arrested by cooling. An activation energy for the presumed double diamond-square-diamond fluxional process is calculated to be ca. 47 kJ mol-1 by analysis of the 1H and 31P NMR spectra of the nickelacarborane. For the molybdacarborane the equivalent activation energy is ca. 40 kJ mol-1 from the 1H spectrum.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C10H16BrN, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 5350-41-4, in my other articles.
