A variety of metal salts are reduced by thermal and photochem. interaction with tetraarylborate salts and with neutral alkyl- and aryl-borane complexes. In the cases of Cu2+, Cu+, Ni2+, Co2+, Pd2+, Pt2+, Ag+, Zn2+, Hg2+, Sn2+, Pb2+ and Rh3+ salts, such photochem. reductions with NaBPh4 led to the deposition of the free metal, while a number of binary mixtures of metal salts led to the codeposition of both metals, sometimes as true alloys, under such photoreductions The arylborate reductants underwent oxidative coupling of the aryl groups to form biaryls in a strictly intra-ionic (for BAr4–) or intramol. (Ar3B) manner, resp. Individual studies of the photochem. of the tetraarylborate anion itself, of cuprous tetraphenylborate and of the triphenylborane-pyridine complex adduced evidence for a gamut of reactive intermediates capable of serving as the photoreductant for metal ions, such as triarylborane radical anions, diarylborate(I) anions or arylborenes, 7-borabicycloheptadiene anions or neutral complexes and finally arylborohydride anions or arylboron hydrides. The role of these intermediates both in the photoinduced skeletal rearrangements of arylboranes and in the concomitant reduction of metal ions is discussed in critical detail.
