nitriles was developed by oxoammoniumsalt (4-acetamido-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate) mediated oxidative conversion of aldehydes with NH4OAc. A variety of aliphatic aldehydes as well as benzaldehydes were converted into the corresponding nitriles in high yields. The nitroxyl radical which is the reduced species of the usedoxoammoniumsalt was recovered by simple acid-base

Reactions of both terminal and cyclic alkenes have been shown to occur in a stereospecifically - manner with deutrerium cyanide when a catalyst system based on Pd(DIOP)2 was used. Reactions of cyclohexene give only the products of equatorial cyanide incorporation.

represents a clean and safe alternative to hydrocyanation processes using toxic HCN gas. Such reactions provide access to pharmaceutically important nitrile derivatives starting with alkenes and alkynes. Herein, an efficient and practical cooperative palladium/Lewis acid-catalyzed transfer hydrocyanation of alkenes and alkynes is presented using 1-methylcyclohexa-2,5-diene-1-carbonitrile as a benign and readily
