A cyclometalated rhodium complex has been shown to perform highly selective and efficient reduction of aldehydes, deriving the hydrogen from methanol. With methanol as both the solvent and hydrogen donor under mild conditions and an open atmosphere, a wide range of aromatic aldehydes were reduced to the corresponding alcohols, without affecting other functional groups.

Reaction of trans-2-chloro-3-methoxy-α-phenylcinnamic acid (1) with KNH2/NH3 gives 4-methoxyphenanthrene-9-carboxylic acid (2).A similar treatment of 1-(2'-chlorophenyl)-2,2-diphenylethylene (15a) affords 9-phenylphenanthrene but its meta-halogenated anal
