Intracellular hydrolysis of the ester is followed by a putative nucleophilic attack on the phosphorus by the negatively charged carboxyl group, resulting in the spontaneous elimination of phenol, producing a highly unstable five-membered ring. A nucleophilic attack from a water molecule opens up this ...
beyond F,O,N) examples of C–H⋯P interactions can be introduced during teaching the chemistry of phosphorus (Hansen, Du, & Kjaergaard, 2014). As shown above, proposing an H-bridge interaction among molecules requires expertise, critical thinking, and previous knowledge about the HBD and HB...
