The photoanation of the bipyrazyl complex Ru(bpz)3(PF6)2, in acetonitrile containing chloride ion, leads to the formation of cis-Ru(bpz)2(CH3CN)Cl+ (maximum quantum yield 0.37), cis-Ru(bpz)2Cl2 (maximum quantum yield 0.001), and an unidentified mono(bipyrazyl)ruthenium(II) derivative. The mechanism of this reaction is discussed. Reaction of M(CO)6 (M = W, Mo) with bipyrazyl yields M(CO)4bpz. The electronic, vibrational, and 1H NMR spectra and electrochemistry of these products were compared with those of their bipyridyl analogues. It is concluded that bipyrazyl is no better a π acceptor than bipyridyl because of weaker σ bonding leaving the metal ion more positvely charged.
