The sun never sets on synthetic methodology- redox neutral organocatalytic Mitsunobu reactions

One of the things I enjoy most about science, and chemistry in particular, is that even processes that are well understood and used routinely, almost without thinking about them, can be re-invented. The allure of discovering new reactions and being at the forefront of a completely new area of research attracts many academics and students,

Intermolecular reductive C-N cross coupling of nitroarenes and boronic acids by P(III) / P(V)=O catalysis

When approaching the synthesis of an aryl- or heteroaryl- amine most people would turn to a suitable transition metal (Pd, Cu or Ni) catalysed C-N cross-coupling reaction- most likely a Buchwald-Hartwig reaction, or, if this has limited success, Ullmann or Chan-Evans-Lam couplings.1 Photoredox approaches using aryloxy amides as a source of amidyl radicals began a trend

Heterocyclic phosphonium salts- powerful intermediates for pyridine coupling

Heterocyclic phosphonium salts- powerful intermediates for pyridine coupling:- I’ve always had a keen interest in phosphorus chemistry and have followed the work of the McNally group at Colorado state on heterocyclic phosphonium salts closely. In late 2016 a paper describing synthesis and application of the so called HetPhos salts for C4 (or C2) functionalisation of
