DOI: 10.1016/j.tet.2021.132185
Abstract: Abstract An alternative mild method for access to 1-aryl-3,3-dimethyl alkyl triazenes is described. This protocol employs the dropwise addition of a methanolic solution of a carboxylate (RCO2M) or carbonate (CO32-) to a gently heated DMF… read more here.

DOI: 10.1021/acsomega.9b03248
Abstract: Tyrosine is an attractive target for chemo- and site-selective protein modification. The particular chemical nature of tyrosine residues allows bioconjugation chemistry with reactive aryl diazonium salts via electrophilic aromatic substitution to produce diazo compounds. In… read more here.
