WebThe alkylation of phthalimide with alkyl halides was first reported in 1884, but in 1887 S. Gabriel realized that the process was a general one and developed a synthesis for primary amines. Henceforward, the mild two-step process for the preparation of primary amines from their corresponding alkyl halides, i.e., alkylation followed by hydrolysis, became … WebThis video shows two examples of synthetic substitution.

WebFeb 15, 2024 · Starting with diboranes with two electron-rich bridging bicyclic guanidinate substituents, we report in this work the rational synthesis of new dicationic symmetrically- and unsymmetrically-substituted diboranes in S N 1-type substitution reactions in which triflato or bromo substituents are replaced by neutral Lewis bases. The scope of such …
WebWe found promising results against prostate (9.6 μM) and colon (13.5 μM) adenocarcinoma cells. We also found a tradeoff between selectivity (up to 3-fold vs. ARPE-19) and inhibition, depending upon the symmetry and bromine-substitution of the molecules, showing up to 20-fold higher selectivity vs. doxorubicin controls.
