Palladium on magnesium oxide is able to allow a one‐pot reaction to synthesize thioethers from thiols and aldehydes formed in situ from the respective alcohol by means of a borrowinghydrogen method. The reaction is initiated by dehydrogenation of the alcohol to give a palladium hydride intermediate and an aldehyde. The latter reacts with a thiol involving most probably the intermediacy of a thionium

substituted benzyl phenyl sulide. The effect of oxygen on quantum yields is best observed after samples are thoroughly outgassed with consecutive freeze-pump-thaw cycles. It is shown that oxygen diminishes the substituenteffect. Upon photolysis of the outgassed samples, the meta-substituted derivatives showed more significant variances than the para derivatives. The meta derivatives are most efficiently

The nucleoside transport inhihitor 6-[(4-nitrobenzyl)thio]-9-(beta-D-ribofuranosyl)purine, NBMPR, has been used successfully in photoaffinity labeling. We have studied the mechanism for photocleavage of the benzyl-sulfur bond by using substituted benzyl phenyl sulfides as analogues of NBMPR. This has enabled us to enhance the photoreactivity of the benzyl-sulfur bond. We have also performed ,,radical clock'' studies with a hexenyl side chain to trap reactive intermediates. The mechanistic interpretation from the substituent and side chain studies is that the benzyl-sulfur moiety is photocleaved via a homolytic pathway.
