BORYLATION OF o-HYDROXYPHENYL PHOSPHORUS DERIVATIVES

Article abstract of DOI:10.1007/BF00965441

The reaction of isobutyl diphenylborate with O,O-diethyl o-hydroxyphenylphosphonate and o-hydroxyphenylphosphine gave 5,6-benzo-2-phenyl-4-ethoxy-4-oxo-1,3,2,4-dioxaboraphosphorinane and o-diphenylboryloxyphenylphosphine, respectively.The borylation only at the α-hydroxyalkyl fragments of bis(β,β,β-trichloro-α-hydroxyethyl)(o-hydroxyphenyl)phosphine and the conversion of the o-boryloxyphenyl phosphorus derivative to an α-boryloxyalkyl derivative upon the action of chloral indicates the greater stability of compounds with the P-C-O-B fragment than that for compounds with the P-C-C-O-B fragment.
