Variable temperature 1 H n.m.r. spectra of pyridine solutions of tetrakis(hydroxymethyl)phosphonium chloride indicate that chemical exchange of methylol groups of the salt with those of the small amount of tris(hydroxymethyl)phosphine formed is the cause of their magnetic equivalence at elevated temperatures. Triethylamine transforms the salt into the phosphine and at least two other phosphorus species which may result from reaction of formaldehyde at oxygen of the phosphine.
