✦ Synopsis

The kinetics of oxidation of D-glucopyranose 6-phosphate and D-ribofuranose 5-phosphate by chromium(V1) in perchloric acid media have been studied by U.V. spectroscopy. Each reaction is first order with respect to [chromium(VI)] and [substrate]. The reactions are acid-catalysed and accelerated by the addition of sodium perchlorate. The mechanism of the reactions is discussed.

6-(Triphenylphosphonio-3Ј-cyclopentadienyl)-2,3,5-trihalocyclohexa-2,5-diene-1,4-diones (2) are a new class of phosphorus containing dyes that behave as weak bases. Mono-protonation occurs at the cyclopentadiene ring leading to three isomers as assessed by NMR. The kinetics of the protonation were s
