✦ Synopsis

N4

[Pd(NH3)4]CI2, calcined at 500°C and reduced in hydrogen at 400°C has been reported as an effective oxidation catalyst using oxygen as oxidant [T. Tatsumi, K.

Yuasa and H. Tominaga, J. Chem. Soc., Chem. Commun., (1992) 1446]. The authors state that benzene can be selectively oxidized to phenol at 25°C. TS1 normally requires H202 as the selective oxidant and in this article the authors imply that in-situ H202 formation takes place from the cofed Hz/02 mixture. Although the rate with Hz/02 is much lower than when H202 is used at the same conditions, the use of oxygen in place of H202 is an exciting development.
