We also found it convenient to perform this reaction using dichloromethane as solvent which usually affords better reaction homogeneity.Reetz, M. T.; Kyung, S. H.; Hullmann, M. "CH3Li/TiCl4: A Non-Basic and Highly Selective Grignard Analogue." Tetrahedron. 1986, 42(11), 2931-2935....

To confirm its structure, we followed the reaction by IR Molecular structure of complex 11 Suitable single crystals of complex 11 were grown from a dichloromethane solution by slow diffusion of pentane at −20 °C. The X-ray diffraction study confirmed the η3-allenyl structure. The ortep ...

The CM product angular distributions from the three reactions are quite different: Li+CH3I favors backward scattering (i.e., a reversal in Li atom direction during the reaction) although the CM distribution is poorly resolved due to unfavorable kinematics; Li+CCl4favors sideways scattering; and ...
To calculate the limiting reagent, enter an equation of a chemical reaction and press the Start button. The reactants and products, along with their coefficients will appear above. Enter any known value for each reactant. The limiting reagent will be highlighted in red. Theoretical yields...
The reaction of Re2O7 with XeF6 in anhydrous HF provides a convenient route to high-purity ReO2F3. The fluoride acceptor and Lewis base properties of ReO2F3 have been investigated leading to the formation of [M][ReO2F4] [M = Li, Na, Cs, N(CH3)4], [K][Re2O4F7], [K][Re...
A plausible reaction mechanismhas been also proposed on the basis of previous reports andthe control experiments.Indoles are ubiquitous heterocycles in nature and represent akind of privileged structural motif of important value indrug discovery, 1 and consequently there are many powerfulmethodologies to...
