Synthesis of α-aryl nitriles through B(C6F5)3-catalyzed direct cyanation of α-aryl alcohols and thiols

Various α-aryl nitriles have been prepared in excellent yield from the corresponding α-aryl alcohols employing 3 mol % of B(C6F5)3 (1) as Lewis acid catalyst and (CH3)3SiCN (TMSCN) as cyanide source. Cyano transfer from TMSCN to alcohol proceeds within short reaction time at rt. α-Aryl thiols also produce corresponding nitriles in good to excellent yield at reflux condition.

Bleaching composition

Bleaching (detergent) compositions are disclosed comprising a peroxide bleaching agent and a novel cationic peroxyacid bleach precursor having at least one of the following groups (A) and (B) : wherein R1 and R2 are each individually H, or a substituent group containing at least one carbon atom, provided that R1 and R2 are not both H. The novel bleach precursor of the cationic nitrile type shows no tendency to deliquesce under normal atmospheric conditions.

THE S- AND N-ADDITION OF THE COMPLEXES OF AMINES WITH SULFUR DIOXIDE TO ELECTROPHILIC ALKENES

The addition of the complexes of amines with sulfur dioxide to acrylonitrile, methacrylonitrile, and crotononitrile was relized.The reactions of acrylonitrile with CH3NH2 -> SO2 and C2H5NH2 -> SO2 complexes take place with the formation of N-alkyl-2-cyanoethanesulfonamides (S-addition of the complexes at the double bond).The electrophilic alkenes react with (CH3)2NH -> SO2 and (C2H5)2NH -> SO2 to form complexes of the substituted β-aminonitriles with sulfur dioxide (N-addition of the complexes at the double bond).
