Manganese-mediated borylation of aryl/heteroaryl diazonium salts emerges as a general and versatile synthetic methodology for the synthesis of the corresponding boronate esters. The reaction proved an ideal testing ground for delineating the Mn species responsible for the photochemical reaction processes, that is, involving either Mn radical or Mn cationic species, which is dependent on the presence of a suitably strong oxidant. Our findings are important for a plethora of processes employing Mn-containing carbonyl species as initiators and/or catalysts, which have considerable potential in synthetic applications.

3-Aminoestrone, a non-natural C-18 steroid, was synthesized by the classical and by a new efficient pathway, the latter using benzophenone imine as an ammonia equivalent in the palladium(0)-catalysed amination of estrone-triflate. This methodology circumv
