X-Ray crystal structure analysis of protonated phenyl-(t-butyl)-phosphinic amide
Abstract
Determination of the crystal and molecular structure of the hydrochloride of phenyl-(t-butyl)-phosphinic amide, [Ph(But)P(O)NH2]2·HCl, shows that the acidic proton is located between the two phosphoryl oxygen atoms, clearly demonstrating preferred O-protonation of the amide function.
