The coupling reactions of a number of alcohols and phenols with alkyl, acyl or benzoyl halides in acetonitrile with cesium fluoride-Celite are described. It has been found that CsF-Celite combinations provide an efficient, convenient and practical method for syntheses of both, ethers and esters.
The reduction of Schlff bases to form secondary amines has been accomplished by catalytic hydrogenatzon' and by various reagents such as maqneslum in 3 methano12, LiAlH4 , 4 and NaBH4 . More recently, [Fe3(C0)12] was reported to effective for the reaction 5 . We found that the reduction of various c
