Abstract

Hydrodehalogenation of aryl chlorides is carried out using NaBR4 in the presence of an Ni-phosphine catalytic system. The nature of the solvent plays a very important role in determining the efficiency of the system: very high dechlorination rates are obtained using ethanol/ pyridine mixtures.

    Samples were collected periodically for analysis over 67 d. Anaerobic reductive dechlorination mechanism of TCC through hydrodehalogenation was also investigated using NaBH4 in the presence of an Ni-phosphine catalytic system as previously reported for other aromatic halides (Scrivanti et al., 1998). Briefly, the catalytic system (0.1 mM of NiCl2(PPh3)2 and 0.2 mM of PPh3) and 5 mM of NaBH4 was added to a 10 mL ethanol/pyridine (9/1) solution of TCC (0.2 mM).

    Suitable dopants can decrease the decomposition temperature of hydrogen storage materials. Some investigations have already been done in experiments [5–7] and theoretical calculations [8,9]. For instance, Nano-Ti, Nano-Ni, etc., can effectively decrease the decomposition temperature of Zn(BH4)2, and the chlorides of Fe, Co, Ni exhibit perfect catalytic activities on the destabilization of LiBH4, and so on.
