The structure of2was determined by X-ray crystallography (Fig.1cand Supplementary Fig.7). This molecule has theC2hsymmetry and, therefore, the bicyclo[1.1.0]tetrasilane moiety has a completely planar structure with the interflap angle between the two cyclotrisilane rings being 180.0°. The dis...
The alkoxide ligand is a particularly attractive spectator or ancillary ligand since the specific choice of R may greatly influence the coordination number of the metal and the binding of a substrate. Moreover, the electron releasing property of the RO- ligand is dependent on the M-0-C angle ...
the more negative temperature coefficient, the larger deviation of this torsion angle from the ideal value of 180° [5]. Recent NMR studies revealed novel long-range deuterium isotope effects on the 13 C and 19 F NMR chemical shifts [6,7]. These effects, caused by deuteration at NAH, ...

Calculate the capacitive reactance, the impedance, and the phase angle(phi) for the mentioned series RC circuit. Convert the given Haworth projection to its acyclic form. How many H <-> H eclipsing interactions would be present if cyclopentane were planar? Assuming an energy cost of...
of ring perimeter and the change of ring bond angle. For nitrocyclopropane∙∙∙HF, the effect of H-bond on the ring strain energy is notable, while for the other complex, it is negligible. Therefore, for nitrocyclopropane∙∙∙HF, the origin of the change of explosive sensitivity...
In which of these organic compounds is an oxygen atom double-bonded to a carbon somewhere other than the end of a carbon chain? a. Alcohol b. Aldehyde c. Ketone d. Alkane What is the bond order of Br2? What is the bond angle in a tetrahedral molecule?...
b. What orbitals are mixed to form this type of hybridization? c. How many of each hybrid orbital is formed? d. What unhybridized o Predict the hybrid orbitals used by the sulfur atom(s) in each of the following. Also predict the molecular structure, i...
The system comprising [RuCl2(p-cymene)]2/1-phenylcyclopentane-1-carboxylic acid (PCCA)/PPh3 together with a large excess of K3PO4 base has once again proven to be a catalyst system of choice, since quantitative conversions of 1 with four.equivalents of 4-bromoacetophenone into arylated ...
