[GRAPHICS]A variety of vic-diols were first successfully cleaved to the corresponding aldehydes with dioxygen catalyzed by RU(PPh3)(3)Cl-2 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)(3)Cl-2/C in PhCF3 at 60 degrees C for 15 h produced heptanal and 1,8-octanedial in 77% and 76% yields, respectively.
