Lignin Models. l-(4-Hydroxy-3-methoxyphenyl)-2-(2-methoxyphcnoxy)propan-1,3-diol (VII). The 4-benzyloxy-a-keto precursor to VII was prepared as previously described (16), Treatment of this compound (70 mg, 0.17 mmole) in THF(2 mL)/H2O(0.1 mL) with 10% Pd/C under H2 (balloon), with stirring, for 3 hours gave a colorless oil (49 mg, 91%) which was shown to be VII by comparison (TLC and NMR) with authentic material. A 70 30 erythroAhreo ratio was indicated by 13C-NMR. The XH and 13C-chemical shifts (CDCI3) have been previously published (17), Compound VII enriched with 13C at Ca was prepared from labeled acetovanillone, which was prepared from guaiacol and acetic acid-l-13C by a procedure analogous with that described previously (16), The 7-13C enriched compound was made by simply utilizing 13C-formaldehyde in the synthesis. 

Mercuric acetate reacts with guaiacol in methyl alcohol or ethyl alcohol—acetic acid solution to yield principally diacetoxymercuri guaiacol and possibly some monomercuri compound.
