title: Oxidative cleavage of vic-diols to aldehydes with dioxygen catalyzed by Ru(PPh3)3Cl2 on active carbon.
abstract: [reaction: see text] A variety of vic-diols were first successfully cleaved to the corresponding aldehydes with dioxygen catalyzed by Ru(PPh3)3Cl2 on active carbon in fair to good yields. For example, treatment of 1,2-octandiol and 1,2-cyclooctanediol with dioxygen in the presence of Ru(PPh3)3Cl2/C in PhCF3 at 60 degrees C for 15 h produced heptanal and 1,8-octanedial in 77% and 76% yields, respectively.
