of vanillin with phosphoryldichlorides. The di(4-hydroxymethyl-2-ethoxyphenyl)phosphates (DHMPP) were prepared by the reduction of DFMPP with potassium borohydride. The 31P-1H coupling in DFMPP (compounds 1a-h) was investigated and the splitting of the 31P signal by the 1H nuclei was observed only with the alkyl DFMPP (1a-e). In the non-decoupled 31P spectra a quartet at −11.3 ppm was seen for la (P-OCH
