Abstract: R4NBF4 effects were studied in 9,10-dicyanoanthracene sensitized photooxidation of 1,4-diphenyl-l,3-butadiene in CH2Cl2.Because of the association of the dipolar salts to form qua-drupoles which can react with exciplex giving radical ions,the photooxidation was accelerated by addition of R4NBF4 and the product distribution was changed.The usage of salt effect in mechanism study and synthesis were discussed.

Key words: electron transfer, salt effect, photooxidation
