چکیده
|
An efficient protocol has been developed for the preparation of a library of benzoxazole,benzimidazole,and benzothiazole derivatives from reactions of acyl chlorides with o-substituted aminoaromatics in the presence of catalytic amount of silica-supported sodium hydrogen sulphate under solvent-free conditions. simple workup procedure,high yield,easy availability,reusability,and use of ecofriendly catalyst are some of the striking features of the present protocol. © 2013 k. ravi kumar et al.
