Self-association of diphenylpnictoginic acids in solution and solid state: covalent vs. hydrogen bonding featured image

Self-association of diphenylpnictoginic acids in solution and solid state: covalent vs. hydrogen bonding

Triphenylpnictogens were oxidized to access diphenylpnictioginic acids Ph2XOOH (X = P, As, Sb, Bi). It was shown that oxidation with chloramine-T does not lead to the cleavage of a …
