Abstract  

m- and p-Chloroanisole were dechlorinated in the presence of a supported noble-metal catalyst (Pd/C or Rh–Pt/C) at 30 °C in a solution of 2-propanol containing NaOH. The addition of a small amount of methanol (1% v/v) to the 2-propanol solution greatly enhanced the rate of dechlorination of p-chloroanisole with Pd/C but retarded the rate with Rh–Pt/C. Other primary alcohols (1% v/v) enhanced m-chloroanisole dechlorination over Pd/C in the following order: methanol (enhancement factor, 10.6) > ethanol (3.3) > 1-propanol (2.1) > 1-butanol (1.0). When a secondary alcohol (2-butanol), tertiary alcohol (t-butyl alcohol), diol (ethylene glycol), or triol (glycerin) was added at 1% (v/v), the dechlorination rates were unchanged or retarded. We found that Pd/C was activated effectively by pretreatment with a solution of 2-propanol/methanol (99:1 v/v) containing NaOH.
