Catalytic hydrogenation of pyrylium salts
Reshetov,Seller,Kriven'ko
, p. 538 - 541 (2007/10/03)
On catalytic reduction of 2,6-diphenylpyrylium salts, hydrogenolysis occurs at the C-O bond with the formation of 1,5-diphenylpentanes. The principal direction of the hydrogenation of 9-phenyl-symoctahydroxanthylium tetrafluoroborate is the formation of a
