WebI was just wondering if it would be hard to theoretically halogenate a DMT molecule at carbon number 5, and then perform a Williamson ether synthesis to create 5 Meo Dmt My question is I’m not really sure what the activation matrix is like on that molecule and how you would direct the halogen to the 5th carbon (meta ortho para) things like that.
WebApr 13, 2024 · Modifying non-precious metal porphyrins at the meso-position is sufficient to further improve the ability to activate O2 and the selectivity of the corresponding redox products. In this study, a crown ether-appended Fe(III) porphyrin complex (FeTC4PCl) was formed by replacing Fe(III) porphyrin (FeTPPCl) at the meso-position. The reactions of … WebIt is known that the oxygen atom of ether is basic, similar to the oxygen atom of alcohol. Thus, the initial reaction between ether and halide produces a protonated ether. The nucleophilic attack of halide ion on this protonated ether leads to cleavage of C-O bond. ... Write the reactions of Williamson synthesis of 2-ethoxy-3-methyl pentane ...
