Abstract:
peri-Substituted naphthalene complexes (Trip2Pn)2Naph (Pn = Sb 1, Bi 2) were synthesised and their redox behaviour investigated. Oxidation of 1 with [Fc][BArF] (BArF = B(C6F5)4) yielded [(Trip2Sb)(TripSb)Naph][BArF] (3) containing the stibane-coordinated stibenium cation [(Trip2Sb)(TripSb)Naph]+. Subsequent reduction of 3 with KC8 yielded distibane (TripSb)2Naph (4). 1-4 were characterised by NMR (1H, 13C) and IR spectroscopy as well as single-crystal X-ray diffraction (sc-XRD), while their electronic structures were analysed by quantum chemical computations.

Alcohols from Carbonyl Compounds: Reduction
Catalytic hydrogenation is similar to the reduction of an alkene or alkyne by adding H2 across the pi bond in the presence of transition metal catalysts like Raney Ni, Pd–C, Pt, or Ru. Aldehydes and ketones can be reduced by this method, often under mild to moderate heat (25–100°C) and...
