Alkylation of indoles with α,β-unsaturated ketones in presence of a clay mineral catalyst. Mn +-Mt (M = Al, Zr) efficiently catalysed the alkylation of activated aromatic compounds (phenol, anisole, etc.) with aldehydes and ketones (Scheme 9.6). A13 +-Mt exhibited significant activity (...
Phenol red, a pH indicator, turns yellow when you breathe into a solution. How does this reaction explain why the solution turned acidic? As a result of the transfer of an electron from a less electronegative atom to a more electronegative atom, (a) the more...
Both ethidium bromide (left over from agarose gel electrophoresis) and salts from buffers can compromise an absorbance measurement (Figure 16), so purification of the DNA by phenol:chloroform extraction followed by ethanol precipitation is crucial.

1a, in which a class of cyclic diazodicarboxamides (triazodiones) reacted selectively and rapidly with the phenol side chain of tyrosine as first developed by the Barbas group for the application in bioconjugate chemistry7,8. Although the development of other methodologies towards the synthesis of...
Protection of some reactive functional groups is possible during polymerization, using known organic chemical methods, such as silanation of alcohol or phenol groups. This expedient and the subsequent deprotection step will, of course, complicate the overall polymerization. Solvents with high dielectric ...
Question: Draw the major product of the reaction of this halide with NaOH. Alkene: An alkene is formed by both the Hoffman rule and the Saytzeff's rule, but the major products of these two are different and depend only upon the base. If the base is so bulky, a less crowded alke...
