Versuchsvorschrift
1-Benzyloxy-4-allyloxy-benzene (20.4 g, 84.9 mmol) dissolved in mesitylene (150 ml) was heated at 165° C. for 48 hr under an argon atmosphere. After cooling to ambient temperature the resulting brown oil was chromatographed over SiO2 (Merck 230-400 mesh) eluting with EtOAc-nHexane (1:9) to afford 2-allyl-4-benzyloxy-phenol (17.45 g, 72.6 mmol, 85%) as a pale yellow oil MS m/e=240.1 (M+).
