Reactions of p-hydroxyphenylphosphine, bis(hydroxymethyl)(p-hydroxyphenyl) phosphine, and bis(hydroxymethyl)(5-allyl-2-ethoxybenzyl)phosphine with nitrogen-containing heterocumulenes were studied. The competitive reactivity of the phenol, phosphine, and hydroxymethyl groups in these reactions was examined.
Phosphonation of 1,1′-binaphthalene-2,2′-diol (BINOL): Synthesis of (R)- and (S)-2,2′-dihydroxy-1,1′-binaphthalene-6,6′-diyldiphosphonic acid
