✦ Synopsis

Redox disproportionation of benzyl alcohol to benzaldehyde and toluene catalysed by the Pd 561 phen 60 (OAc) 180

(phen 1,10-phenanthroline) giant cluster 1 under anaerobic conditions was found, whereas in an O 2 atmosphere cluster 1 catalyses the oxidation of benzyl alcohol to benzaldehyde and inhibits further oxidation of the latter. A study of the AIBN-initiated and non-initiated oxidation of benzyl alcohol, sec-butyl alcohol and styrene in the presence of cluster 1 revealed that cluster 1 performs three functions in the oxidation reactions: 1) catalysis of polar oxidation of the substrates with O 2 , 2) termination of the chains of radical oxidation, and 3) catalysis of redox disproportionation.
