摘要：
A series of benzoxazole and benzothiazoles was readily prepared from the reaction of ortho-aminophenol/ortho-aminothiophenol and aldehydes using solid silica supported ferric chloride (SiO2-FeCl3) as catalyst followed by oxidation with H2O2 under ambient conditions. Some of advantages of this method are a simple and convenient procedure, easy purification, and shorter reaction times. Supplemental materials are available for this article.
