Greener and Sustainable Applications of Phosphorous and Sulfur Ylides

Abstract

The present review highlights relevant recent examples (2013-2018) of sustainable synthetic reactions involving phosphorus and sulfur ylides. These examples include catalytic, halide- and base-free Wittig olefination reactions and P-ylides as CO2 activators. They also include sustainable protocols for the synthesis of S-ylides and recent applications of these C1 synthons as carbene precursors and in selected rearrangement reactions
