Reactions of p-hydroxyphenylphosphine and functionally substituted bis(hydroxymethyl)phosphines with heterocumulenes

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.

Synthesis of new phosphines and P-heterocycles from phosphonates containing allyl group

Addition of phenylphosphine to allylphosphonate followed by reduction of the resulting diphosphonate gives a new branched phosphine, bis(3-phosphinopropyl)phenylphosphine. Its reaction with paraform and p-toluidine yields oligomeric 3-[3-(propylenophenylphosphino)propyl]-1,5-di-p-tolyl-1,5,3, 7-diazadiphosphacyclooctane. Diethyl (5-allyl-2-ethoxybenzyl)phosphonate was obtained. Its reduction gives unsaturated (5-allyl-2-ethoxybenzyl)phosphine. This product adds two moles of formaldehyde to give bis-(hydroxymethyl)(5-allyl-2-ethoxybenzyl)phosphine. The reaction of this compound with p-toluidine yielded, depending on the conditions, the corresponding bis(aminomethyl)phosphine, 1,3,5-diazaphosphorinane, and 1,5,3,7-diazadiphosphacyclooctane, and also their derivatives containing allyl substituents.
