Mixing it up : The first persistent mixed phosphorus‐sulfur bisylide has been synthesized (see scheme). Its formation was clearly demonstrated by its chemical reactivity, such as by methylation and complexation with Cu I ions. DFT calculations on a model compound indicate that they are highly polarized species as a result of the interaction of the lone pairs of electrons on the central carbon atom with only the phosphonium function.
