The influence of n-tetrabutylammonium tetrafluoroborate(R₄NBF₄) on the conversion and product distribution is studied in 9,10-dicyanoanthracence(DCA) sensitized photooxidation of 3,4-dihydro-2H-pyran (DHP).The source of singlet oxygen in this reaction is discussed and electron transfer mechanism is confirmed by the observation of salt effect.
