Subject nickel-mediated

Recently, chloro-, bromo-, and iodoben-zenes have been subjected to electroreduction using Ni(0) complex mediators to yield biphenyl. NiCl2L2 and NiBr2L2 [L= P(Ph)3, (Ph)2PCH2CH2P(Ph)2] have been used as catalysts [259-265]. Pro-tic media such as alcohols, that is, methanol, ethanol or alcohol-water mixtures are found to be suitable solvents for achieving the electrosynthesis of biaryls from aryl halides according to a procedure that involves a catalytic process by nickel-2,2 -bipyridine complexes [266]. Electrochemical cross-coupling between... 

The relationship between constitutional or irritant-mediated barrier impairment and contact sensitization is complex and reciprocal. Contact-sensitive subjects, especially nickel-sensitive ones, are reported to have an increased susceptibility to irritants. Van der Valk et al. showed a higher TEWL increase following SLS...
