8. 92X i, RuCl p (PPh; j) 3-t-BuOOH, ii, Pd (PPh3 14 acyl cyanide 4 in 87% yield. The decarbonylation of 4 with Pd (PPh3), catalyst gave nitrile 5 in 99% yield. The similar treatment of 4-(benzoy1oxy) benzaldehyde cyanohydrin (6) gave acyl cyanide 7 in 80% yield. The palladium-catalyzed reaction of 7 gave the corresponding nitrile 8 in 92% yield. In these reactions, benzyloxy and benzoyloxy groups are retained under the reaction ...
